2. Infestation (n.): an article is used before the gap so we need to use a noun in the gap and based on meaning “infestation” is correct.
3. Rose (v.): based on English word order after the subject we must use a verb and based on meaning “rose” is correct.
4. Reproduction (n.): an article is used before the gap so we need to use a noun in the gap and based on meaning “reproduction” is correct.
5. Below (prep.): the gap is between a verb and a noun so we need to use a preposition in the gap and based on meaning “below” is correct.
