[Q]: I read this background article the other day: Scientists think that the earliest flowers attracted insects and other animals, which spread pollen from flower to flower. This greatly increased the efficiency of fertilization over wind-spread pollen, which might or might not actually land on another flower. To take better advantage of this "animal labor," plants evolved traits such as brightly colored petals to attract pollinators. In exchange for pollination, flowers gave the pollinators nectar. I am facing a new situation today: Scientists studied two groups of plants. Group F had plants with flowers, group W had plants that fertilize over wind- spread pollen. Flowering plants were more efficient. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group of plants has a lower fertilization efficiency?

[A]: group W

[Q]: I read this background article the other day: According to current definitions, all planets must revolve around stars; thus, any potential "rogue planets" are excluded. In the Solar System, all the planets orbit the Sun in the same direction as the Sun rotates (counter-clockwise as seen from above the Sun's north pole). At least one extrasolar planet, WASP-17b, has been found to orbit in the opposite direction to its star's rotation. The period of one revolution of a planet's orbit is known as its sidereal period or year. A planet's year depends on its distance from its star; the farther a planet is from its star, not only the longer the distance it must travel, but also the slower its speed, because it is less affected by its star's gravity. No planet's orbit is perfectly circular, and hence the distance of each varies over the course of its year. The closest approach to its star is called its periastron (perihelion in the Solar System), whereas its farthest separation from the star is called its apastron (aphelion). As a planet approaches periastron, its speed increases as it trades gravitational potential energy for kinetic energy, just as a falling object on Earth accelerates as it falls; as the planet reaches apastron, its speed decreases, just as an object thrown upwards on Earth slows down as it reaches the apex of its trajectory.Each planet's orbit is delineated by a set of elements: I am facing a new situation today: John is an amateur astronomer. Last week he was observing the sky with his telescope. First he pointed his telescope at planet Mars. He noted it as case A. Then he pointed his telescope to planet Jupiter, which is farther form the Sun than Mars is. He noted it as case C. Finally, he pointed the telescope to a faraway planet called WASP-17b. He noted that as case B. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which case would see counter-clockwise movement, case A or case B?

[A]: case A

[Q]: I read this background article the other day: A godet (/ode/ or /odt/)[1] is an extra piece of fabric in the shape of a circular sector which is set into a garment, usually a dress or skirt.[2] The addition of a godet causes the article of clothing in question to flare, thus adding width and volume.[3] Adding a godet to a piece of clothing also gives the wearer a wider range of motion.[4] I am facing a new situation today: Dan is a dance instructor. In an upcoming dance competition he has to send two groups of students, group A and group B. He dressed group A students with godet. But he didn't dress group B students with godet. There are two categories of dance, category C and category D, in the dance competition. Category C requires lots of motion, but category D does not required much motion. Dan has to decide which of his student groups would compete in category C and which group to compete in category D. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would group A be suitable or unsuitable for category C competition?
****
[A]: suitable

[Q]: I read this background article the other day: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih I am facing a new situation today: Pete lived in Alaska, but visited his friend Julia from Hawaii very often. They had many mutual interests, including geology and earthquakes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person lived closer to Niahu island?
****
[A]:
Julia
