In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'. 

I was shocked (A)/ to see how much my grandmother had aged (B)/ since the last time we visited her. (C)/ No Error (D)

The correct answer is option 4 i.e. D.

• The given sentence has no errors.
• The sentence is in the past tense so we use the past tense form of the verbs i.e. shocked and aged.
• 'Since' has been used to refer to a point of time in the past.

Confusion Points

• There might be confusion regarding why 'we' is used in the (C) part of the sentence and not 'I'.
• Both 'we' and 'I' are correct.
• The speaker is talking about his/her own feeling (was shocked) when the last time he/she visited her.
• It can be that the speaker went along with a group of family members, and hence 'we' is referred to correctly.
• Also, the usage of 'aged' is used correctly. We do not have to use 'many'. "I was shocked to see how many my grandmother had aged since the last time we visited her." is grammatically incorrect.
