A certain one-day seminar consisted of a morning session and an aftern...

Statement (1): 3/4 of the people attended both sessions.

If 3/4 of the people attended both sessions, it means that 1 - 3/4 = 1/4 of the people attended only one session. However, we don't know which session they attended. Therefore, statement (1) alone does not provide enough information to answer the question.

Statement (2): 7/8 of the people attended the afternoon session.

If 7/8 of the people attended the afternoon session, it means that 1 - 7/8 = 1/8 of the people attended only the morning session. This statement gives us a specific proportion of people who attended the morning session only, regardless of the total number of people attending. Therefore, statement (2) alone is sufficient to answer the question.

Based on the analysis above, the correct answer is B: Statement (2) alone is sufficient, but statement (1) alone is not sufficient to answer the question asked.

A certain one-day seminar consisted of a morning session and an aftern...

Given:
- The seminar consists of a morning session and an afternoon session.
- There are 128 people attending the seminar.
- Each person attended at least one of the two sessions.

To find:
- The number of people who attended the morning session only.

Statement 1: 3/4 of the people attended both sessions.
- Let the number of people who attended both sessions be x.
- From the given statement, we know that x = 3/4 * 128.
- Therefore, the number of people attending both sessions is 96.

Statement 2: 7/8 of the people attended the afternoon session.
- Let the number of people who attended the afternoon session be y.
- From the given statement, we know that y = 7/8 * 128.
- Therefore, the number of people attending the afternoon session is 112.

Analysis of statements:
- From statement 1, we know that 96 people attended both sessions.
- From statement 2, we know that 112 people attended the afternoon session.
- However, neither statement provides information about the number of people who attended the morning session only.

Conclusion:
- Neither statement alone is sufficient to determine the number of people who attended the morning session only.
- Therefore, the correct answer is option B - Statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question asked.
