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.

[Q]: Paragraph- Sent 1: The factory is highly automated and designed to shift flexibly to produce many different kinds of chips to suit demand.
Sent 2: "The diversity is the big difference with this plant," said Richard Doherty, president of Envisioneering, a research firm.
Sent 3: "It gives IBM the capability to make so many different kinds of custom chips, and the world is going to custom chips."Sent 4: The 140,000-square-foot plant is a testament to advanced manufacturing technology.
Sent 5: The 300-millimeter silicon wafers -- about the size of a standard pizza -- are shuttled around the facility in enclosed plastic pods, which ride on overhead tracks.
Sent 6: They drop down from wires automatically into machines, sheathed in stainless steel and glass, for each stage of processing and fabrication.
Sent 7: Throughout the 500 processing steps, which typically last 20 days, the wafers are not touched by human hands.
Sent 8: The circuits etched into the chips are less than one thousandth the width of a human hair.
Sent 9: Human operators are there to monitor the systems, catch errors and fine-tune the production process for maximum efficiency.
Sent 10: Because each of the hundreds of processing machines is self-enclosed, and essentially airtight, the uniforms operators wear are less constricting than in the previous generation of chip plants, which looked like space suits.
Sent 11: The operators at the East Fishkill factory wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper.
Sent 12: They look more like workers in a bakery.
Sent 13: Yes, said Richard Brilla, director of the new facility, "but the donuts are a lot more costly here."Sent 14: Each wafer, holding hundreds of chips, is worth $6,000 to $10,000 apiece, depending on what insulation, circuitry and materials are used.
Question: Why do operators at the East Fishkill factory look like workers in a bakery? (A) As the wafers are the size of a standard pizza (B) Since the processing machines are self-enclosed (C) Since they seem to wear space suits (D) Since they wear light uniforms, shoe coverings and hair nets (E) This is because they wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper (F) They make donuts.
[A]: D, E.

[Q]: Paragraph- Sent 1: Conduction is the transfer of thermal energy.
Sent 2: It occurs between objects or substances that are touching.
Sent 3: Thermal conductors are materials that are good conductors of heat.
Sent 4: Thermal insulators are materials that are poor conductors of heat.
Sent 5: Both conductors and insulators have important uses.
Sent 6: Convection is the transfer of thermal energy.
Sent 7: This occurs as particles move within a fluid.
Sent 8: The fluid may be a liquid or a gas.
Sent 9: The particles within the fluid transfer energy by moving from warmer to cooler areas.
Sent 10: They move in loops.
Sent 11: These loops are called convection currents.
Sent 12: Radiation is the transfer of thermal energy by waves.
Sent 13: These waves can travel through empty space.
Sent 14: When the waves reach objects, the heat is transferred to the objects.
Sent 15: Radiation is how the Sun warms the Earths surface.
Question: In order for Convection to happen, should you use a conductor or an insulator? (A) An insulator (B) A conductor because insulators are bad conductors of heat (C) A conductor.
[A]: B, C.

[Q]: Paragraph- Sent 1: We drove about a great deal--the country at the back of Deauville, going away from the sea, is lovely--very like England--charming narrow roads with high banks and hedges on each side--big trees with spreading branches meeting overhead--stretches of green fields with cows grazing placidly and horses and colts gambolling about.
Sent 2: It is a great grazing and breeding country.
Sent 3: There are many haras (breeding stables) in the neighbourhood, and the big Norman posters are much in demand.
Sent 4: I have friends who never take their horses to the country.
Sent 5: They hire for the season a pair of strong Norman horses that go all day up and down hill at the same regular pace and who get over a vast amount of country.
Sent 6: We stopped once or twice when we were a large party, two or three carriages, and had tea at one of the numerous farmhouses that were scattered about.
Sent 7: Boiling water was a difficulty--milk, cider, good bread and butter, cheese we could always find--sometimes a galette, but a kettle and boiling water were entirely out of their habits.
Sent 8: They used to boil the water in a large black pot, and take it out with a big spoon.
Sent 9: However, it amused us, and the water really did boil.
Question: Who hires Norman horses? (A) The speaker's friends (B) The farmers.
[A]:
A.
