Hi!
Check-up
Doctor: Now, I’d like to check your blood pressure. Man: OK. Doctor: Put your arm up like this. Man: Aha. Doctor: I’m going to wrap a cuff around it ← Original text (without any punctuation mark) Man: Aha. Doctor: Which will feel quite tight, but only for a moment. Man: OK.
Doctor: I’m going to wrap a cuff around it ←
Which punctuation mark should be placed after it?
1- Nothing (The original text is correct)
2- Full stop “.”
3- Comma “,”
4- Semicolon “;”
Explanation:
The sentence “I’m going to wrap a cuff around it” is a complete sentence with a subject (“I”) and a predicate (“am going to wrap a cuff around it”). Therefore, it should end with a full stop to indicate that the sentence is complete.
Correct: I’m going to wrap a cuff around it. Not correct: I’m going to wrap a cuff around it (missing punctuation) Not correct: I’m going to wrap a cuff around it, (comma implies more is coming, but the next sentence starts a new idea) Not correct: I’m going to wrap a cuff around it; (semicolon is unnecessary here)
Let me know if you want help with more punctuation examples!
Rezaforu, it doesn’t seem to be a relative pronoun, it IS a relative pronoun, introducing a relative clause (which was really annoying) adding more information about the antecedent (16 hours for our plane).
