Question

finding error. (a). knowledge need hardwork (b). devotion and sincere from us​

Answer 1

Answer:

a) knowledge need hardwork.

Error: "knowledge" is singular in sense here, so it will agree with a singular verb.

Valid sentence: Knowledge needs hardwork.

b) devotion and sincere from us

Error: "Devotion" and "sincere" are two nouns joined by "and". But "sincere" is a verb. So it will be replaced by the noun form of "sincere" that is "sincerity".

Valid sentence/phrase: devotion and sincerity from us.
