Question

Karim persuaded ____ spend the weekend at his home.
a)that his parents
b)his parents
c)his parents to
d)to his parents​

Answer 1

Karim persuaded his parents to spend the weekend at his home.

* The verb used in this sentence is 'persuaded' and it can't be followed by any preposition or pronoun/determiner.

So we reject the options (a) and (d).

* Both the options (b) and (c) can be a probable answer but we choose option(c) as the answer.

* The phrase 'persuaded his parents spend' is incorrect as 'parents' should be followed by a preposition.

Answer 2

Karim persuaded his parents to spend the weekend at his home.

Option (c)

Explanation:

• The word persuaded is an action. A word that shows an action is called as a verb in the grammatical sense.
• This verb cannot be followed by all prepositions. This makes options a) and d) eliminate as ‘that’ and ‘to’ are prepositions.
• If the option ‘b’ is taken the whole sentence will look like Karim persuaded his parents spend ... which makes the sentence incomplete. Therefore the correct sentence is when using the option in c).
