You are given a paragraph, a question and some answer options (associated with "A", "B", "C", "D", etc.) You need to list all the correct answer options with their associated letters (e.g. "A" can be a valid answer). Note that sometimes, more than one option can answer the question correctly and completely. In those cases, please generate all such options separated by a comma (e.g. "A, B" is a valid answer). Do not generate anything else apart from one or more of the following characters: 'A', 'B, 'C', 'D', etc.

Input: Consider Input: Paragraph- Sent 1: If you have a mass of 50 kg on Earth, what is your weight in newtons?
Sent 2: An object with more mass is pulled by gravity with greater force.
Sent 3: Mass and weight are closely related.
Sent 4: However, the weight of an object can change if the force of gravity changes.
Sent 5: On Earth, the force of gravity is the same everywhere.
Sent 6: So how does the force of gravity change?
Sent 7: It doesnt if you stay on Earth.
Sent 8: What if we travel to another planet or moon in our solar system?
Sent 9: Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure.
Sent 10: They were the first humans to walk on the moon.
Sent 11: An astronaut weighs less on the moon than he would on Earth.
Sent 12: This is because the moons gravity is weaker than Earths.
Sent 13: The astronauts mass, on the other hand, did not change.
Sent 14: He still contained the same amount of matter on the moon as he did on Earth.
Sent 15: If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon.
Sent 16: If his mass on Earth was 80 kg, what would his mass have been on the moon?
Sent 17: [Figure 3].
Question: This unit of measurement can be used instead of pounds. What is it? (A) Kilograms (B) Newtons.

Output: A, B.

Input: Consider Input: Paragraph- Sent 1: 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.
Sent 2: 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.
Sent 3: 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.
Sent 4: 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.
Sent 5: 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".
Sent 6: 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.
Sent 7: She took on the virtues of a traditional Chinese female, particularly forbearance".
Sent 8: But if she were really an ideal wife, why could she not live happily with her human mate?
Sent 9: Her dangerous sexuality is the key.
Sent 10: 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.
Sent 11: But this term, which is relatively speaking, a neologism (The earliest uses were around the beginning of the 20th century.
Question: Could Madame White Snake live out a normal life with her mate, why or why not? (A) No, because of her evil character (B) Yes (C) No, because of her dangerous sexuality (D) Yes, because she made an ideal wife (E) She was really an ideal wife and could live comfortably and happily with her human mate forever.

Output: C.

Input: Consider Input: Paragraph- Sent 1: The day was just breaking, as I left the tower; though it was still too dark in the house to be able to see without a light, and I took one of the study candles with me on my 'round.
Sent 2: By the time I had finished the ground floor, the daylight was creeping in, wanly, through the barred windows.
Sent 3: My search had shown me nothing fresh.
Sent 4: Everything appeared to be in order, and I was on the point of extinguishing my candle, when the thought suggested itself to me to have another glance 'round the cellars.
Sent 5: I had not, if I remember rightly, been into them since my hasty search on the evening of the attack.
Sent 6: For, perhaps, the half of a minute, I hesitated.
Sent 7: I would have been very willing to forego the task--as, indeed, I am inclined to think any man well might--for of all the great, awe-inspiring rooms in this house, the cellars are the hugest and weirdest.
Sent 8: Great, gloomy caverns of places, unlit by any ray of daylight.
Sent 9: Yet, I would not shirk the work.
Sent 10: I felt that to do so would smack of sheer cowardice.
Sent 11: Besides, as I reassured myself, the cellars were really the most unlikely places in which to come across anything dangerous; considering that they can be entered, only through a heavy oaken door, the key of which, I carry always on my person.
Question: What was the last room he had to check? (A) The bedroom (B) The last room on the ground floor (C) The study (D) The cellars (E) The guest room.
Output: D.
