Question

Fill in the blank with the most appropriate word.
After I ____ my dinner, I typed my report.
A) Had
B) Have
C) Had had
D) Will have

Answer 1

Hint: When we speak about the past and want to refer back to an earlier era, the past perfect tense is used. Certain auxiliary verbs are used in past perfect tense.

Complete answer:
Given sentence is in the past perfect tense because of 'Typed' which means the sentence is in the past tense. Here, the word 'after' means that he/she ate dinner before the subject 'typed' his/her study. Thus, the activity of eating dinner with regard to the past was already complete. Only a perfect tense may imply a full action.
Lets see options :
Option A : ‘had’ is used in simple past tense but sentence is in past perfect tense using had will make sentences grammatically incorrect thus this option is wrong too.

Option B : ‘have’ is used in simple present tense but sentences in past perfect tense, using have will make sentences grammatically incorrect thus this option is wrong too.

Option C : ‘had had’ is used in past perfect tense where the sentence is speaking about the past and wants to refer back to an earlier past time . using had had in given sentence will make it complete and meaningful thus this option is correct

Option D : ‘will have’ is used in simple future tense but sentences in past perfect tense, using will have will make sentences grammatically incorrect thus this option is wrong too.

Therefore option ‘C’ is the correct answer.

Note:
i) The use of 'had had' is grammatically accurate and properly conforms to the Past Perfect Tense rules.
ii) If the verb to follow is 'have' in accordance with the syntax, the past participle form of "have" is used, which is "had" Then “had had” is used.
