Look at the blank with the number 9 in the passage. which of these answers correctly completes the sentence? a) will live b) has lived c) have lived d) will have lived

A. will live

Explanation:

The best type of tense to complete the above passage is a future tense.

The conversation in the passage links an event or occurrence that is currently happening to that which is yet to happen.

So, a future tense is required to complete this passage.

Another point to take note of is; the reference point in this passage is "child and children". As used in this passage, the "child and children" are only imaginary (as they are yet to be perceived).

So, the best option (from a through d) is option A.

The incomplete sentence in the passage becomes

To keep these superb predators in the world our children and grandchildren will live in, we must learn to make room for other living things to use Earth's limited resources.

the correct answer is a. how to make proposal that works.

indeed, the register is quite formal and the tone is especially objective as it avoids the use of the first and second person singular (i, you) and opts instead for the third person plural which is more impersonal and focuses on the data and the argument that is being developed by the author. the formality adds the impression of respectability to the work and the impersonality adds objectivity to it.
