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 Q]: Paragraph- Sent 1: The highest point of a wave is the crest.
Sent 2: The lowest point is the trough.
Sent 3: The vertical distance between a crest and a trough is the height of the wave.
Sent 4: Wave height is also called amplitude.
Sent 5: The horizontal distance between two crests is the wavelength.
Sent 6: Both amplitude and wavelength are measures of wave size.
Sent 7: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows.
Sent 8: The greater each of these factors is, the bigger a wave will be.
Sent 9: Some of the biggest waves occur with hurricanes.
Sent 10: A hurricane is a storm that forms over the ocean.
Sent 11: Its winds may blow more than 150 miles per hour!
Sent 12: The winds also travel over long distances and may last for many days. 
Question: Other factors being equal, why would an ocean wave be larger if the wind were blowing 150 miles per hour than if it the wind were blowing 100 miles per hour? (A) Wave height is also called amplitude (B) Because a faster wind hits ocean directly (C) The greater the wind, the bigger will be the wave (D) The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows (E) Because the faster wind speed will cause the wave to be larger than a slower wind speed (F) Because a faster wind lasts longer (G) It increases the amplitude of the wave.
[EX A]: C, D, E, G.

[EX Q]: Paragraph- Sent 1: Do all plants live on the land?
Sent 2: Some plants do live in the water.
Sent 3: To do this, they have evolved special traits.
Sent 4: Plants that live in water are called aquatic plants.
Sent 5: Living in water has certain benefits.
Sent 6: There is certainly plenty of water!
Sent 7: The plant does not need special traits to absorb, transport, or conserve water.
Sent 8: They do not need a large root system.
Sent 9: They do not need a strong stem to hold up the plant.
Sent 10: The plant uses the water for support.
Sent 11: Dont think water plants have it easy, though.
Sent 12: They also face challenges.
Sent 13: Living in water isnt that easy.
Sent 14: They do need some special traits to survive.
Sent 15: It is tough for the plant to reproduce.
Sent 16: Pollination by wind or animals cant happen under water.
Sent 17: Sunlight cannot reach very far beneath the waters surface.
Sent 18: Some aquatic plants have floating flowers and leaves. 
Question: Plants that live in water have special benefits and they don't need what things that plants on land do need? (A) Special traits to absorb, transport or conserve water (B) Roots or a large stem system (C) Long roots and more water (D) Sunlight (E) Flowers and leaves.
[EX A]:
A, B, C.
