Explanation:

Sampling bias occurs when the sample is not representative of the population. Here, the newspaper staff surveyed students at specific sports - games (basketball, football, volleyball). Students at a basketball game are more likely to favor basketball, and so on. This means the sample is not randomly selected from all students but from specific sport - related events, so it is not representative of all students' favorite sports.

Answer:

These samples are biased because the newspaper staff went to a basketball game, football game, and volleyball match to interview the students.
