Explanation:

Define two-way table requirements

A two-way table organizes bivariate data to show the relationship between two categorical variables. Each variable must represent distinct, mutually exclusive categories (often binary "yes/no" questions) rather than open-ended preferences or multiple non-standardized choices.

Evaluate the options for categorical variables

• Option 1: "whether the relative was born in Korea" (Yes/No) and "whether the relative speaks Korean" (Yes/No). Both are clear, binary categorical variables suitable for a two-way table.
• Option 2: "what their favorite Korean meal is" is an open-ended question with many possible unique answers, making it unsuitable for standard row/column headings.
• Option 3: "what city in Korea is their favorite" is also open-ended with many potential answers.
• Option 4: Both variables are open-ended questions with many possible unique answers.

Select the correct option

Option 1 is the only choice where both variables are clearly defined, binary categorical variables suitable for the row and column headings of a two-way table.

Answer:

• (A) whether the relative was born in Korea; whether the relative speaks Korean (Correct answer)
• (B) whether the relative was born in Korea; what their favorite Korean meal is
• (C) what city in Korea is their favorite; whether the relative speaks Korean
• (D) what city in Korea is their favorite; what their favorite Korean meal is
