To analyze the statement and the conclusions:
Statement:
Just about everyone in Germany has been on a diet at one time or another, and millions of them have learned that the weight they lose is all too easily regained. Still, despite their frustration, few question the wisdom of dieting.
Conclusions:
I. Germans should stop dieting.
II. Germans do not learn from experience.
Analysis:
- Conclusion I: Germans should stop dieting.
This conclusion is a suggestion and cannot be drawn directly from the statement. The statement mentions frustration but does not imply that they should stop dieting.
- Conclusion II: Germans do not learn from experience.
The statement indicates that many have learned about the ease of regaining weight but still choose to diet, which suggests they have learned but continue to pursue dieting despite their experiences. Therefore, this conclusion is also not accurate.
Conclusion:
Since neither conclusion follows logically from the statement, the correct answer is **D: If neither conclusion I nor II follows.
