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: If you have a mass of 50 kg on Earth, what is your weight in newtons?
Sent 2: An object with more mass is pulled by gravity with greater force.
Sent 3: Mass and weight are closely related.
Sent 4: However, the weight of an object can change if the force of gravity changes.
Sent 5: On Earth, the force of gravity is the same everywhere.
Sent 6: So how does the force of gravity change?
Sent 7: It doesnt if you stay on Earth.
Sent 8: What if we travel to another planet or moon in our solar system?
Sent 9: Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure.
Sent 10: They were the first humans to walk on the moon.
Sent 11: An astronaut weighs less on the moon than he would on Earth.
Sent 12: This is because the moons gravity is weaker than Earths.
Sent 13: The astronauts mass, on the other hand, did not change.
Sent 14: He still contained the same amount of matter on the moon as he did on Earth.
Sent 15: If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon.
Sent 16: If his mass on Earth was 80 kg, what would his mass have been on the moon?
Sent 17: [Figure 3].
Question: How does the force of gravity change? (A) It changes with change in weight (B) It changes with change in mass (C) The force of gravity changes depending on where you are in the solar system (D) The force of gravity never changes (E) This is because the moons gravity is weaker than Earths- it changes when you go to a place with less gravity.

Output: B, C, E.

Input: Consider Input: Paragraph- Sent 1: Sally had a very exciting summer vacation.
Sent 2: She went to summer camp for the first time.
Sent 3: She made friends with a girl named Tina.
Sent 4: They shared a bunk bed in their cabin.
Sent 5: Sally's favorite activity was walking in the woods because she enjoyed nature.
Sent 6: Tina liked arts and crafts.
Sent 7: Together, they made some art using leaves they found in the woods.
Sent 8: Even after she fell in the water, Sally still enjoyed canoeing.
Sent 9: She was sad when the camp was over, but promised to keep in touch with her new friend.
Sent 10: Sally went to the beach with her family in the summer as well.
Sent 11: She loves the beach.
Sent 12: Sally collected shells and mailed some to her friend, Tina, so she could make some arts and crafts with them.
Sent 13: Sally liked fishing with her brothers, cooking on the grill with her dad, and swimming in the ocean with her mother.
Sent 14: The summer was fun, but Sally was very excited to go back to school.
Sent 15: She missed her friends and teachers.
Sent 16: She was excited to tell them about her summer vacation.
Question: How did Sally feel about returning to school, and how did she feel about telling her friends and teachers about her summer vacation (A) Sally was excited to go back to school, and she was excited to tell her friends and teachers about her summer vacation (B) She was excited to go back to school and missed her friends and teachers and wanted to tell them about her summer vacation (C) She was sad to go back to school but was excited to tell her friends and teachers about her summer vacation.

Output: B.

Input: Consider Input: Paragraph- Sent 1: Women and minorities appear to be benefiting from greater employment opportunities in the United States, but discrimination remains a significant problem, according to a study to be released today by two professors at the Rutgers School of Law in Newark.
Sent 2: The study, which extrapolated from federal data on about 200,000 large and midsize employers, concludes that about two million workers were affected by intentional discrimination in 1999.
Sent 3: Roughly a third of the employers studied appeared to have discriminated against women or minorities in at least one job category, the authors said The study was based on information collected from employers by the Equal Employment Opportunity Commission from 1990 through 1999 on so-called EEO-1 forms.
Sent 4: The husband-and-wife team of Alfred W. and Ruth G. Blumrosen then looked at how many women or minority workers a company employed in different job categories compared with how many were employed at other companies in the same industry in the same geographic area.
Sent 5: They described a company as an intentional discriminator if its employment of women or minorities was at least two standard deviations from the average.
Sent 6: Legally, companies are presumed to discriminate if their employment numbers are far below the norm.
Sent 7: About 22,000 employers were identified as "hard core" discriminators.
Sent 8: These companies employed below-average numbers of women and minorities for 10 years and their hiring of women or minorities was so far below the averages that there was only one chance in a hundred that the discrimination occurred randomly.
Sent 9: The study also found rising employment for women and minorities, suggesting significant progress in the workplace.
Sent 10: The names of the companies are confidential and were not known to the researchers.
Sent 11: The professors expect to make their study available through a Web site, www.eeo1.com.
Sent 12: The Blumrosens, who were instrumental in setting up the E.E.O.C. in 1965, also say the government should make more active use of their data.
Sent 13: The commission said it did not comment on draft reports.
Question: What were the names of the companies found to be discriminatory and where can the report be found? (A) The names of the companiers were not released, but the report is expected to be relased on website www.eeo1.com (B) Unknown to researchers, www.eeo1.com (C) Confidential, www.eeo1.com (D) The companies are listed in the study at www.eeo1.com (E) Known to researchers at Rutgers (F) The study can be found at bls.org.
Output: A, B, C, D.
