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.

Ex Input:
Paragraph- Sent 1: Have you ever seen an egg?
Sent 2: Some animals do not have live births.
Sent 3: Instead, they lay eggs.
Sent 4: The eggs contain the embryo.
Sent 5: The embryo matures in the egg.
Sent 6: With time, it will hatch.
Sent 7: Some animals hatch and do not need care from their parents.
Sent 8: They are ready to live on their own.
Sent 9: Other animals will still need the care of their parents.
Sent 10: Sea turtles break out of their shells.
Sent 11: They immediately walk to the ocean.
Sent 12: They do this with no help from an adult.
Sent 13: Birds stay in the nest for many weeks.
Sent 14: They are cared for by their parents.
Sent 15: They leave the nest when they are strong enough to fly.
Sent 16: Some animals give birth to live offspring.
Sent 17: Animals like horses, cows, and whales give live birth.
Sent 18: Their offspring are born looking like mini adults.
Question: How do sea turtles behave after being born? (A) Sea turtles break out of their shells.

Ex Input:
Paragraph- Sent 1: The center of an atom is held together by powerful forces.
Sent 2: This gives them a huge amount of stored energy.
Sent 3: This type of energy is called nuclear energy.
Sent 4: This energy can be released and used to do work.
Sent 5: This happens in nuclear power plants where they split apart the nucleus of an atom.
Sent 6: This splitting apart is called nuclear fission.
Sent 7: Another type of nuclear energy happens in the Sun.
Sent 8: Here the atoms nuclei are not split apart.
Sent 9: Instead, the nuclei of the atoms are fused, or joined together.
Sent 10: This process is called nuclear fusion.
Sent 11: Some of the suns energy travels to Earth.
Sent 12: This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.
Question: How do nuclear fission and nuclear fusion differ? (A) Fission joins atoms nuclei (B) The nucleus splits in nuclear fission, but does not in nuclear fusion (C) Fusion comes from the moon and fission from the sun (D) Fission splits atoms nuclei (E) Fission fuses the nucleus and fusion splits the nucleus (F) Fusion joins atoms nuclei (G) Nuclear fission splits the nucleus and fusion fuses the nucleus (H) Fission causes photosynthesis and fusion doesn't (I) In nuclear fission, the nucleus of the atom is split apart. In nuclear fusion, atoms are fused, or joined together (J) Fusion splits atoms nuclei.

Ex Output:
B, D, F, G, I.

Ex Input:
Paragraph- Sent 1: Fossils give clues about major geological events.
Sent 2: Fossils can also give clues about past climates.
Sent 3: Fossils of ocean animals on the top of a mountain?
Sent 4: Ocean animals have been found on the Earths tallest mountain.
Sent 5: Its hard to believe, but it is true.
Sent 6: These fossils were found at the top of Mt. Everest.
Sent 7: Mt. Everest is the highest mountain on Earth.
Sent 8: These fossils showed that this entire area was once at the bottom of a sea.
Sent 9: It can only mean that Mt. Everest was uplifted.
Sent 10: In fact, the entire Himalaya mountain range was raised.
Sent 11: It was forced up from the collision of two continents.
Sent 12: Fossils of plants are found in Antarctica.
Sent 13: Now, Antarctica is almost completely covered with ice.
Sent 14: Plants do not grow in Antarctica.
Sent 15: According to fossils, they once did.
Sent 16: This means that Antarctica was once much warmer than it is now.
Sent 17: These fossils tell us about Antarcticas past climate.
Question: What does the fact that fossils have been found on the top of Mt. Everest? (A) Mount Everest was under the seas (B) There are no fossils up there (C) Mt. Everest was lifted up from the collision of two continents (D) Mount Everest is the tallest mountain (E) Animals live on Mount Everest (F) The fossils have been carried up there (G) The fossils were blown up there (H) The entire area of Mt. Everest used to be on the ocean floor.
