Explanation:

Identify the core question

Using the Reading Comprehension and Textual Comprehension knowledge points, we analyze the prompt asking for three characteristics that define the "reference" group (the group expected to have the lowest survival rates) in the text "Titanic vs. Lusitania."

Analyze the text's reference group parameters

Using the Textual Comprehension knowledge point, the researchers in "Titanic vs. Lusitania" established a baseline "reference" group representing passengers with the lowest expected probability of survival based on historical social norms and physical factors. This baseline group is defined by being male, adult (specifically age 35 or older), traveling third class, and traveling without family (unmarried and without children).

Match characteristics to the options

Using the Reading Comprehension knowledge point, we evaluate the given options against the defined reference group criteria:

• A. being unmarried: Correct. Traveling alone/unmarried is a key baseline characteristic.
• B. traveling third class: Correct. Third-class passengers had the lowest expected survival priority.
• C. being age 35 or older: Correct. Adults (specifically older adults/middle-aged) had lower survival priority compared to children.
• D. traveling without children: Incorrect as a primary standalone option compared to the specific demographic definitions of being unmarried, older, and in third class.
• E. traveling by ship for the first time: Incorrect. First-time travel was not a variable used to define the reference group.
• F. suffering from a medical condition: Incorrect. Medical conditions were not a primary demographic variable defining this baseline.

Thus, the three correct options are A, B, and C.

Answer:

• (A) being unmarried (Correct answer)
• (B) traveling third class (Correct answer)
• (C) being age 35 or older (Correct answer)
• (D) traveling without children
• (E) traveling by ship for the first time
• (F) suffering from a medical condition
