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: Tocqueville thought the conquest of Algeria was important for two reasons: first, his understanding of the international situation and France's position in the world, and, second, changes in French society.
Sent 2: Tocqueville believed that war and colonization would "restore national pride, threatened", he believed, by "The gradual softening of social mores" in the middle classes.
Sent 3: Their taste for "material pleasures" was spreading to the whole of society, giving it "an example of weakness and egotism".
Sent 4: Applauding the methods of General Bugeaud, Tocqueville went so far to claim that "war in Africa is a science.
Sent 5: Everyone is familiar with its rules and everyone can apply those rules with almost complete certainty of success.
Sent 6: One of the greatest services that Field Marshal Bugeaud has rendered his country is to have spread, perfected and made everyone aware of this new science."Sent 7: Tocqueville advocated racial segregation in Algeria with two distinct legislations, one for European colonists and one for the Arab population.
Sent 8: Such a two-tier arrangement would be fully realised with the 1870 Cremieux decree and the Indigenousness Code, which extended French citizenship to European settlers and Algerian Jews, whereas Muslim Algerians would be governed by Muslim law and restricted to a second-class citizenship.
Question: What did Tocqueville believe was spreading and which society was it spreading through? (A) France's taste for material pleasures (B) A deadly virus (C) Their taste for "material pleasures".

Output: A, C.

Input: Consider Input: Paragraph- Sent 1: You may wonder if there are other examples of static discharge.
Sent 2: The answer is yes.
Sent 3: Lightning is a form of static discharge.
Sent 4: It is much more dramatic than what happens between you and the door knocker, but it is the same principle.
Sent 5: You can see how it occurs in the following diagram and animation.
Sent 6: You have no doubt seen lightning in a rainstorm.
Sent 7: What does lighting have to do with static electricity?
Sent 8: As it turns out, everything!
Sent 9: During a rainstorm, clouds develop regions of different charges.
Sent 10: This happens due to the movement of air molecules, water drops, and ice particles.
Sent 11: The negative charges are concentrated at the base of the clouds.
Sent 12: The positive charges are concentrated at the top.
Sent 13: The negative charges repel electrons on the ground below.
Sent 14: The ground then becomes positively charged.
Sent 15: Over time the differences increase.
Sent 16: Eventually the electrons are discharged.
Sent 17: This is what we see as lightning.
Sent 18: You can watch an awesome slow-motion lightning strike below.
Question: Is lightning a form of static discharge? (A) No (B) Yes (C) Agree (D) Disagree.

Output: B, C.

Input: Consider Input: Paragraph- Sent 1: Sometimes traits can vary from parent to offspring.
Sent 2: These changes are due to mutations.
Sent 3: Mutations are a random change.
Sent 4: Mutations are natural.
Sent 5: Some mutations are harmful.
Sent 6: In this case, the organism may not live to reproduce.
Sent 7: The trait will not be passed onto offspring.
Sent 8: Others variations in traits have no effect on survival.
Sent 9: Can some mutations be good for a living thing?
Sent 10: Other mutations can have great benefits.
Sent 11: Imagine being the first moth that can blend into its background.
Sent 12: It would have a better chance of survival.
Sent 13: A living thing that survives is likely to have offspring.
Sent 14: If it does, it may pass the new trait on to its offspring.
Sent 15: Thats good news for the offspring.
Sent 16: The offspring may be more likely to survive.
Sent 17: Mutations are one way living things adapt to new conditions.
Question: What can cause traits to vary? (A) Parents (B) Mutations (C) Blending in.
Output: A, B.
