Question

My uncle just....... (arrive) from Kolkata.

Answer 1

My uncle just arrived from Kolkata.

Answer 2

My uncle just arrived from Kolkata. This sentence is written in simple past tense, which indicates a work done before now.

In English language, it is a basic form of tense that is often indicated with second form of the verb.

'Arrive' is the first form and its second form is verb.

The word 'just' indicates that uncle has already arrived.

So, I used 'arrived' to complete the sentence.
