In the following question, the first and the last parts of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts P, Q, R, and S. These four parts are not given in their proper order. Read the sentence/passage and find the most logical order of the parts between 1 and 6.
1. Email has changed modern communication. P: It is faster than traditional letters. Q: Instant messaging is also gaining popularity. R: Emails allow file sharing and formal contact. S: However, they may lack personal touch. 6. Choosing the right medium depends on context.

Correct option is A

Option (a) is the correct order of the given sentences.
· After the opener “Email has changed…”, P gives the first key advantage (speed).
· R adds a second, formal/functional advantage (file sharing, formality), keeping the focus on email.
· The connector “However” in S logically introduces a contrast (lack of personal touch) after listing positives.
· Q then widens the lens to another medium (instant messaging), paving the way for the general concluding line about choosing the right medium.
· Thus, 1 – P R S Q – 6 forms a coherent flow: pros → con → alternative → conclusion.
