The correct answer is: Only conclusion I follows.
The statement says that modern man influences his destiny by the choices he makes, unlike in the past. This does not mean that there were no choices available to man in the past, or that there was no desire to influence destiny in the past. It simply means that the choices available to man are more numerous and varied today, and that man is more aware of his ability to influence his own destiny.
Conclusion I follows from the statement because it is a logical consequence of the fact that modern man has more choices available to him. Conclusion II does not follow from the statement because it is not a logical consequence of the fact that modern man has more choices available to him. It is possible that man desired to influence his destiny in the past, but was unable to do so because he did not have the same range of choices available to him as he does today.
Here are some additional details about each option:
- Option A: Only conclusion I follows. This is the correct answer.
- Option B: Only conclusion II follows. This is not the correct answer because conclusion II does not follow from the statement.
- Option C: Either I or II follows. This is not the correct answer because conclusion II does not follow from the statement.
- Option D: Neither I nor II follows. This is not the correct answer because conclusion I follows from the statement.
- Option E: Both I and II follow. This is not the correct answer because conclusion II does not follow from the statement.
