Explanations
1. Adventures are the essence of life – more the number of adventures you have, more beautiful your life gets.

2. If you act as soon as the iron is hot, and without consideration, you will miss your opportunity and be considered a fool.

3. It was unwise of him (not wise of him) to declare war on India. And he obeyed Bhutto; he did not disobey Bhutto.

4. One should not always act as soon as one gets an opportunity without thinking about the consequences of the actions. So statement 1 is wrong. Fools act without thinking. So statement 3 is also wrong.

5. The passage keeps harping on thought-out action that is at the right time and place, and produces the maximum impact.
