Question: In this novel, the protagonist lies about what happened to an amethyst brooch so she can go to a picnic. That protagonist makes up names like Willowmere for locales around her village and inadvertently gets her friend Diana Barry drunk on "raspberry cordial." (*) For 10 points, name this novel about a redheaded orphan adopted by Marilla and Matthew Cuthbert of Avonlea on Prince Edward Island, a novel by Lucy Maud Montgomery.
Answer: Anne of Green Gables

Anne of Green Gables is a 1908 novel by Canadian author Lucy Maud Montgomery (published as L. M. Montgomery). Written for all ages, it has been considered a classic children's novel since the mid-20th century. Set in the late 19th century, the novel recounts the adventures of 11-year-old orphan girl Anne Shirley sent by mistake to two middle-aged siblings, Matthew and Marilla Cuthbert, who had originally intended to adopt a boy to help them on their farm in the fictional town of Avonlea in Prince Edward Island, Canada. The novel recounts how Anne makes her way through life with the Cuthberts, in school, and within the town.
Since its publication, Anne of Green Gables has been translated into at least 36 languages and has sold more than 50 million copies, making it one of the best-selling books worldwide. It was the first of many novels; Montgomery wrote numerous sequels, and since her death another sequel has been published, as well as an authorized prequel titled Before Green Gables. This prequel was written in 2008 by Budge Wilson to celebrate the 100th anniversary of the book series. The original book is taught to students around the world.
The book has been adapted as films, television films, and animated and live-action television series. Musicals and plays have also been created, with productions annually in Canada, Europe and Japan.

Question: This state of matter is the initial and final phase in regelation, and it is to the left of the triple point on phase diagrams. This starting point for sublimation is the most common state for elements at room temperature and pressure. One type of it is amorphous, though it generally is characterized by an orderly pattern on molecules. For 10 points, name this state that includes crystals, the endpoint of freezing.
Answer: solids

Solid is one of the four fundamental states of matter along with liquid, gas, and plasma. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity (as in rigid bodies) and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. The atoms in a solid are bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice), or irregularly (an amorphous solid such as common window glass). Solids cannot be compressed with little pressure whereas gases can be compressed with little pressure because the molecules in a gas are loosely packed.
The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials, as well as the science of identification and chemical composition.

Question: Darwin predicted the existence of a Madagascar moth after observing one of these structures, which have separate male/female types in dioecious [dy-oh-EE-shus] species. The parts of this occur in multiples of three in monocots and many use (*) nectar to attract pollinators. One mature part of this becomes the fruit, and it has stamen and carpel reproductive organs. For 10 points, name this structure found in angiosperm plants, often surrounded by petals.
Answer: {flower} [do not prompt on \"plant\"]

A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower, petals that attract pollinators, and reproductive organs that produce gametophytes, which in flowering plants produce gametes. The male gametophytes, which produce sperm, are enclosed within pollen grains produced in the anthers. The female gametophytes are contained within the ovules produced in the carpels. 
Most flowering plants depend on animals, such as bees, moths, and butterflies, to transfer their pollen between different flowers, and have evolved to attract these pollinators by various strategies, including brightly colored, conspicuous petals, attractive scents, and the production of nectar, a food source for pollinators. In this way, many flowering plants have co-evolved with pollinators to be mutually dependent on services they provide to one another—in the plant's case, a means of reproduction; in the pollinator's case, a source of food. 
When pollen from the anther of a flower is deposited on the stigma, this is called pollination. Some flowers may self-pollinate, producing seed using pollen from a different flower of the same plant, but others have mechanisms to prevent self-pollination and rely on cross-pollination, when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma. This pollination does not require an investment from the plant to provide nectar and pollen as food for pollinators. Some flowers produce diaspores without fertilization (parthenocarpy). After fertilization, the ovary of the flower develops into fruit containing seeds.
Flowers have long been appreciated by humans for their beauty and pleasant scents, and also hold cultural significance as religious, ritual, or symbolic objects, or sources of medicine and food.

Question: Three bearded boarders threaten lawsuits after being scared off by the main character of this work. That protagonist has a sister named Greta who wants to study violin at the conservatory, and he dies after his father throws an apple at him that becomes stuck in his back. (*) For 10 points, name this work in which Gregor Samsa wakes up one day to find that he has been changed into a bug, a work by Franz Kafka.
Answer: The Metamorphosis

The Metamorphosis (German: Die Verwandlung) is a novella by Franz Kafka published in 1915. Its title has also been translated as The Transformation. One of Kafka's best-known works, The Metamorphosis tells the story of  salesman Gregor Samsa, who wakes one morning to find himself inexplicably transformed into a huge insect (German: ungeheueres Ungeziefer, lit. "monstrous vermin") and struggles to adjust to this condition. The novella has been widely discussed among literary critics, who have offered varied interpretations. In popular culture and adaptations of the novella, the insect is commonly depicted as a cockroach. 
With a length of about 70 printed pages over three chapters, it is the longest of the stories Kafka considered complete and published during his lifetime. The text was first published in 1915 in the October issue of the journal Die weißen Blätter under the editorship of René Schickele. The first edition in book form appeared in December 1915 in the series Der jüngste Tag, edited by Kurt Wolff.

Question: This quantity can be measured by a psychrometer (sye-KRAH-meht-er) or a hygrometer. It can be computed as a ratio using either mixing ratio or partial pressure of water. At its maximum, the amounts of water evaporating and condensing are in equilibrium. For 10 points, water content divided by capacity gives what measure of moisture in the air, often expressed as a percent?
Answer: {relative humidity} [or {RH}]

Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present.
Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at 30 °C (86 °F), but only 8 g of water per cubic metre of air at 8 °C (46 °F).
Three primary measurements of humidity are widely employed: absolute, relative, and specific. Absolute humidity is expressed as either mass of water vapor per volume of moist air (in grams per cubic meter) or as mass of water vapor per mass of dry air (usually in grams per kilogram). Relative humidity, often expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature. Specific humidity is the ratio of water vapor mass to total moist air parcel mass.
Humidity plays an important role for surface life. For animal life dependent on perspiration (sweating) to regulate internal body temperature, high humidity impairs heat exchange efficiency by reducing the rate of moisture evaporation from skin surfaces. This effect can be calculated using a heat index table, or alternatively using a similar  humidex.
The notion of air "holding" water vapor or being "saturated" by it is often mentioned in connection with the concept of relative humidity. This, however, is misleading—the amount of water vapor that enters (or can enter) a given space at a given temperature is almost independent of the amount of air (nitrogen, oxygen, etc.) that is present. Indeed, a vacuum has approximately the same equilibrium capacity to hold water vapor as the same volume filled with air; both are given by the equilibrium vapor pressure of water at the given temperature. There is a very small difference described under "Enhancement factor" below, which can be neglected in many calculations unless great accuracy is required.

Question: During one of these events, what is observed is based on the viewer's location relative to the path of totality. Viewers of them might see the annulus or corona, if they are standing in the antiumbra. Viewers standing in the penumbra will see a partial form, while during a total one, the corona may be seen. For 10 points, name this event in which the moon appears to block out the sun.
Answer: {solar eclipse} [prompt on eclipse]

A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially. Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years.
If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Moon's orbit is tilted at about 5 degrees to Earth's orbit, its shadow usually misses Earth. Solar (and lunar) eclipses therefore happen only during eclipse seasons, resulting in at least two, and up to five, solar eclipses each year, no more than two of which can be total. Total eclipses are rarer because they require a more precise alignment between the centers of the Sun and Moon, and because the Moon's apparent size in the sky is sometimes too small to fully cover the Sun.
An eclipse is a natural phenomenon. In some ancient and modern cultures, solar eclipses were attributed to supernatural causes or regarded as bad omens. Astronomers' predictions of eclipses began in China as early as the 4th century BC; eclipses hundreds of years into the future may now be predicted with high accuracy. 
Looking directly at the Sun can lead to permanent eye damage, so special eye protection or indirect viewing techniques are used when viewing a solar eclipse. Only the total phase of a total solar eclipse is safe to view without protection. Enthusiasts known as eclipse chasers or umbraphiles travel to remote locations to see solar eclipses.

Question: This building was constructed with help from Hiram (HYE-ruhm), King of Tyre ("TIRE"). It contained two large pillars named Jachin (JAH-hin) and Boaz. It was ostensibly built on Mount Moriah, which is now home to the Dome of the Rock. This building housed the Ark of the Covenant. After it was destroyed by Nebuchadnezzar (NEH-boo-kah-NEZZ-er), it was rebuilt, only to be destroyed again in 70 CE. For 10 points, identify this place of worship first built by Solomon.
Answer: {temple of Jerusalem} [accept temple of Solomon before "Dome of the Rock;" prompt on temple]

The Temple in Jerusalem, or alternatively the Holy Temple (Hebrew: בֵּית־הַמִּקְדָּשׁ, Modern: Bēt haMīqdaš, Tiberian: Bēṯ hamMīqdāš; Arabic: بيت المقدس, Bayt al-Maqdis), refers to the two religious structures that served as the central places of worship for Israelites and Jews on the modern-day Temple Mount in the Old City of Jerusalem. According to the Hebrew Bible, the First Temple was built in the 10th century BCE, during the reign of Solomon over the United Kingdom of Israel. It stood until c. 587 BCE, when it was destroyed during the Babylonian siege of Jerusalem. Almost a century later, the First Temple was replaced by the Second Temple, which was built after the Neo-Babylonian Empire was conquered by the Achaemenid Persian Empire. While the Second Temple stood for a longer period of time than the First Temple, it was likewise destroyed during the Roman siege of Jerusalem in 70 CE.
Projects to build the hypothetical "Third Temple" have not come to fruition in the modern era, though the Temple in Jerusalem still features prominently in Judaism. As an object of longing and a symbol of future redemption, the Temple has been commemorated in Jewish tradition through prayer, liturgical poetry, art, poetry, architecture, and other forms of expression.
Outside of Judaism, the Temple (and today's Temple Mount) also carries a high level of significance in Islam and Christianity. One of the early Arabic names for Jerusalem is Bayt al-Maqdis, which preserves the memory of the Temple. The Temple Mount is home to two monumental Islamic structures, the Dome of the Rock and Al-Aqsa Mosque, which date to the Umayyad period. The site, known to Muslims as the "Al-Aqsa Mosque compound" or Haram al-Sharif, is considered the third-holiest site in Islam. The Christian New Testament and tradition hold that important events in Jesus' life took place in the Temple, and the Crusaders attributed the name "Templum Domini" ("Temple of the Lord") to the Dome of the Rock.

Question: In one common lab demo, a balloon is shattered after being treated with nitrogen in this form. At room temperature and standard pressure, only bromine and mercury are in this phase. These substances are used to fill a tube in thermometers and barometers. They take the shape of their container, but do not expand to fill it, unlike gases. For 10 points, name this state of matter that can boil and is produced by melting.
Answer: liquid phase [or liquids]

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. It is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Unlike a gas, a liquid maintains a fairly constant density and does not disperse to fill every space of a container.
Although liquid water is abundant on Earth, this state of matter is actually the least common in the known universe, because liquids require a relatively narrow temperature/pressure range to exist. Most known matter in the universe is either gas (as interstellar clouds) or plasma (as stars).

Question: When this substance is used, it often leaves behind a liquid with naphthalene and various phenols. The lowest rank of this type of substance, formed from peat, is lignite, while higher grades are classified as anthracite or the bituminous type. Plant remains over a long period of time transform into this sedimentary rock. For 10 points, name this substance which is used to generate electricity after it is mined out of the ground.
Answer: {coal}

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.
Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times.
Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron and steel-making and other industrial processes burn coal.
The extraction and use of coal causes premature death and illness. The use of coal damages the environment, and it is the largest anthropogenic source of carbon dioxide contributing to climate change. Fourteen billion tonnes of carbon dioxide were emitted by burning coal in 2020, which is 40% of the total fossil fuel emissions and over 25% of total global greenhouse gas emissions. As part of worldwide energy transition, many countries have reduced or eliminated their use of coal power. The United Nations Secretary General asked governments to stop building new coal plants by 2020. Global coal use was 8.3 billion tonnes in 2022. Global coal demand is set to remain at record levels in 2023. To meet the Paris Agreement target of keeping global warming below 2 °C (3.6 °F) coal use needs to halve from 2020 to 2030, and "phasing down" coal was agreed upon in the Glasgow Climate Pact.
The largest consumer and importer of coal in 2020 was China, which accounts for almost half the world's annual coal production, followed by India with about a tenth. Indonesia and Australia export the most, followed by Russia.

Question: During this battle, Senlac Hill was the site of a defensive position set up by housecarls. The losing side's forces had been weakened in a previous battle against Harold Hardrada at Stamford Bridge. The winning side's commander claimed to be the rightful successor to Edward the Confessor. King (*) Harold Godwinson was killed during this battle. For 10 points, name this 1066 battle in which William of Normandy conquered England.
Answer: Battle of Hastings

The Battle of Hastings was fought on 14 October 1066 between the Norman-French army of William, the Duke of Normandy, and an English army under the Anglo-Saxon King Harold Godwinson, beginning the Norman Conquest of England. It took place approximately 7 mi (11 km) northwest of Hastings, close to the present-day town of Battle, East Sussex, and was a decisive Norman victory.
The background to the battle was the death of the childless King Edward the Confessor in January 1066, which set up a succession struggle between several claimants to his throne. Harold was crowned king shortly after Edward's death, but faced invasions by William, his own brother Tostig, and the Norwegian King Harald Hardrada (Harold III of Norway). Hardrada and Tostig defeated a hastily gathered army of Englishmen at the Battle of Fulford on 20 September 1066, and were in turn defeated by Harold at the Battle of Stamford Bridge five days later. The deaths of Tostig and Hardrada at Stamford Bridge left William as Harold's only serious opponent. While Harold and his forces were recovering, William landed his invasion forces in the south of England at Pevensey on 28 September 1066 and established a beachhead for his conquest of the kingdom. Harold was forced to march south swiftly, gathering forces as he went.
The exact numbers present at the battle are unknown as even modern estimates vary considerably. The composition of the forces is clearer: the English army was composed almost entirely of infantry and had few archers, whereas only about half of the invading force was infantry, the rest split equally between cavalry and archers. Harold appears to have tried to surprise William, but scouts found his army and reported its arrival to William, who marched from Hastings to the battlefield to confront Harold. The battle lasted from about 9 am to dusk. Early efforts of the invaders to break the English battle lines had little effect. Therefore, the Normans adopted the tactic of pretending to flee in panic and then turning on their pursuers. Harold's death, probably near the end of the battle, led to the retreat and defeat of most of his army. After further marching and some skirmishes, William was crowned as king on Christmas Day 1066.
There continued to be rebellions and resistance to William's rule, but Hastings effectively marked the culmination of William's conquest of England. Casualty figures are hard to come by, but some historians estimate that 2,000 invaders died along with about twice that number of Englishmen. William founded a monastery at the site of the battle, the high altar of the abbey church supposedly placed at the spot where Harold died.
