Question:
Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter. After reading the above, is "They hear through air molecules in their spaceships." the correct answer to the question "How do astronauts hear?"?

Answer:
yes

Question:
Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter . After reading the above, is "Interplanetary spacecraft" the correct answer to the question "Balboa, Leonardo da Vinci, and Isaac Newton are all types of what?"?

Answer:
no

Question:
Tropical climates are found around the equator. These climates have warm temperatures year round. Tropical climates may be very wet or wet and dry. Tropical wet climates occur at or very near the equator. They have high rainfall year round. Tropical rainforests grow in this type of climate. Tropical wet and dry climates also occur near the equator. They receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season. The main plants are grasses. Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier. Deserts can get less than 25 centimeters of rain per year. Thats less than 10 inches per year. How much rain do you get at your house? After reading the above, is "Very wet or wet and dry with warm temperatures around" the correct answer to the question "What are the climates around the equator like?"?

Answer:
yes

Question:
Madame White Snake: East Asian Femme Fatale of Old The Chinese legend of Madame White Snake, the snake demon that takes human form and becomes the wife of a man, has exerted a lasting influence over East Asian folktales and fiction for centuries. Two quintessential novellas, "The Lust of the White Serpant" from Ugetsu Monogatari by the Japanese author Ueda Akinari and "Eternal Prisoner under Thunder Peak Pagoda" a traditional Chinese story, are both relatively complex and demonstrate not only the evolution of the White Snake figure to become a more believable human, but also what aspects may have given her enduring appeal. While both these stories are ostensibly morality tales about the dangerous beauty of this femme fatale, the true source of pleasure from these narratives is the femme fatale's transgressive behavior, not her eventual punishment for it. Early tales of Madame White Snake appeared in China as early as the Song Dynasty, and initially her portrayal was fairly direct, as a villainous demon who drains the life force out of her human husband. But over time, characterizations of her became more complex, and the persona of Madame White Snake became more sympathetic, and perhaps even a model of the ideal Confucian wife, particularly in "Pagoda". Whalen Lai notes, "She was a loving wife, a caring mother, rescuer of her family from the first flood, and, at that point, a general benefactor of man. She took on the virtues of a traditional Chinese female, particularly forbearance". But if she were really an ideal wife, why could she not live happily with her human mate? Her dangerous sexuality is the key. Femme fatale might seem an unusual term to apply to a character from pre-modern Chinese and Japanese literature who may exemplify the virtues of an ideal Confucian wife, since it is primarily associated with film characters, particularly those of the film noir genre. But this term, which is relatively speaking, a neologism (The earliest uses were around the beginning of the 20th century After reading the above, is "Virtuous" the correct answer to the question "Why was it hard for Madame White snake to be the ideal wife?"?

Answer:
no
