Answer:
The answer is indeed letter A) For big cats to be saved, we must work together.
Step-by-step explanation:
Wordiness happens when we take longer than what is necessary to get to the point. It's a result of redundant expressions, or simply the use of too many words. Let's analyze the sentence provided:
For big cats to be saved, they must be saved by all of us working together.
As we can notice, there is unnecessary repetition inside the sentence. Since the first clause already introcudes the topic of saving big cats, there is no need for the second clause to repeat that information. If we eliminate the repeated phrase and change the rest of the sentence so that it makes sense, the problem of wordiness will be solved.
The only option that does that in an appropriate manner is letter A. The repetition is removed and the sentence is adapted to make sense:
For big cats to be saved, we must work together.
Options B, C, and D still present a problem of wordiness; they merely change a few a words, but the some form of repetition is still there.
