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: Earth processes have not changed over time.
Sent 2: The way things happen now is the same way things happened in the past.
Sent 3: Mountains grow and mountains slowly wear away.
Sent 4: The same process is at work the same as it was billions of years ago.
Sent 5: As the environment changes, living creatures adapt.
Sent 6: They change over time.
Sent 7: Some organisms may not be able to adapt.
Sent 8: They become extinct.
Sent 9: Becoming extinct means they die out completely.
Sent 10: Some geologists study the history of the Earth.
Sent 11: They want to learn about Earths past.
Sent 12: They use clues from rocks and fossils.
Sent 13: They use these clues to make sense of events.
Sent 14: The goal is to place things in the order they happened.
Sent 15: They also want to know how long it took for those events to happen.
Question: What are the goals of geologists? (A) To place things in the order they happened (B) The goal is to place things in the order they happened (C) Make lots of money (D) To know how long it took for those events to happen (E) Make money (F) Learn about eath's past (G) Earth processes (H) Learn from the past.

Output: A, B, D, F, H.

Input: Consider Input: 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.

Output: C, D, E, G.

Input: Consider Input: Paragraph- Sent 1: For much of the world, the Algarve is synonymous with Portugal, yet the Portuguese will tell you the exact opposite: the region has little in common with the rest of the country.
Sent 2: The southern stretch of coast is more reminiscent of a North African landscape than a European one.
Sent 3: It has no cosmopolitan cities, like Lisbon and Porto, which are farther north.
Sent 4: Most of Portugal is known for quaint towns, medieval castles, and grand palaces.
Sent 5: The Algarve is more recognizable for impenetrable blocks of tourist apartments, hotels, and meticulously manicured golf courses.
Sent 6: And beaches.
Sent 7: Think Algarve and the mind pictures long, glorious stretches of golden sands, secluded coves framed by odd ochre-colored rock formations, and deep green waters.
Sent 8: With about 160 km (100 miles) of coastline, Portugal's southern province is one of Europe's premier beach destinations.
Sent 9: The occasionally chilly ocean is the Atlantic, but the Algarve has a sultry Mediterranean feel.
Sent 10: Its consistent climate is the best in Portugal, and one of the kindest in the world: more than 250 days of sunshine a yearmore than almost any other international resort area.
Sent 11: The moderating effect of the Gulf Stream produces a fresh springtime breeze throughout winter, and in late January and February, white almond blossoms blanket the fields.
Sent 12: In summer the heat is intense but rarely unbearable, and regardless, beautiful beaches and innumerable pools are always just a dive away.
Sent 13: Magnificent year-round weather has made the Algarve a huge destination for sporting vacations.
Sent 14: Superb golf facilities aboundseveral with tees dramatically clinging to cliffs and fairways just skirting the edge of the oceanand horseback riding, tennis, big-game fishing, sailing, and windsurfing are immensely popular.
Sent 15: Sports, beaches and hospitable weathernot to mention easily organized package vacationsare surely the reasons the Algarve receives as many visitors as the rest of Portugal in its entirety.
Sent 16: But it's not just international tourists that descend on the Algarve; many Portuguese from Lisbon and elsewhere in the north have holiday homes and spend their summer vacations here.
Sent 17: The coast is neatly divided into the rugged Barlavento to the west and the flat beauty of Sotavento to the east.
Sent 18: West is where you'll find the famous orange cliffs and surreal eroded rock stacks.
Question: What land has no cosmopolitan cities, like Lisbon and Porto which are farther north? (A) Paris (B) Porto (C) The Algarve (D) South Africa (E) West coast (F) North Africa (G) Lisbon.
Output: C.
