Answer:
Your answer would be that the sentence could be rewritten as follows: While I was playing basketball in the driveway, my ball was punctured by a cactus.
Explanation:
The sentence above contains a dangling modifier. A dangling modifier is a phrase or clause that is not clearly and logically related to the word or words it modifies. In this case, the dangling modifier error occurs because the sentence does not specify anything to which the modifier can refer. Consequently, the sentence means that the ball is the one playing basketball in the driveway.
The dangling modifier can be corrected in the following way: change the dangling modifier phrase to a subordinate clause, creating a subject and a verb; then, leave the sentence as it is. Thus, you should introduce the personal pronoun <em>I</em> for the sentence to mean that the one playing basketball in the driveway is the speaker. (see 1).
