Help the exhausted IT technician complete his final report of the day by selecting the correct grammatical options.
It's no use _________________________ about the server crash now; the damage is already done. Furthermore, there's really no point _________________________ to recover the corrupted data without a valid backup.
complaining
The phrase "it's no use" is directly followed by a gerund (-ing form). Adding the preposition "in" or using an infinitive ("to complain") is incorrect.
in trying
The phrase "there's no point" is followed by the preposition "in" + a gerund. Using an infinitive ("to try") is a common mistake!
