Answer:
1. convert
2. selection
3. choice

5. response.
Step-by-step explanation:
1. Please _________ (convert) your numbers to percentages.
The blank above expects an action word (verb) since the sentence expresses a need to do something - a need to convert some numbers to percentages.
Now since the base word given in bracket is in its verbal form, it can be used directly. So to fill in the blank, we have;
[Please convert your numbers to percentages.]
2. The ________ (select) for the competition took place yesterday.
The blank expects a noun since it has been preceded by a definite article "The". But the base word given in bracket is in the verbal form, it needs to be converted into its noun form. Therefore, select becomes selection
So to fill in the blank, we have;
[The selection for the competition took place yesterday.]
3. We have to make a choice between eating healthy food and junk food.
The blank expects a noun since it has been preceded by an indefinite article "a". But the base word given in bracket is in the verbal form, it needs to be converted into its noun form. Therefore, choose becomes choice
To fill in the blank, we have;
[We have to make a choice between eating healthy food and junk food.]
4. She _______ (research) the topic before she gave the presentation.
The blank above expects an action word (verb) since the first part of the sentence follows the subject, verb, object rule. i.e "She" is the subject, the blank should be the verb and "the topic" is the object.
The base word given in bracket is in its verbal form and so could fill the blank. However, the second part of the sentence illustrates that the action happened in the past. Therefore, to follow one of the rules of tenses, the blank has to be filled with the simple past of the base word. i.e research becomes researched
To fill in the blank, we have;
[She researched the topic before she gave the presentation.]
