Choose the most appropriate option to fill in the blank:____ our flig…

The correct answer is Option (1) → After, Despite

Linking words of time and contrast:

• After (conjunction of time) joins two clauses and shows that one event came before another: first the flight was delayed, then the connection was missed.
• Despite (preposition of contrast) means in spite of; it is followed by a noun or an -ing form, not by a full clause: "Despite being delayed".
• This sentence: blank 1 links the delay and the missed connection in time, so "After"; blank 2 shows a contrast (delayed, yet a good trip) and is followed by "being delayed", so "Despite".
• Complete sentence: After our flight from Delhi to Mumbai was delayed because of bad weather, we missed our connection to Dubai and had to spend six hours at the airport. Despite being delayed, we still had a good trip.
  Example: Despite feeling tired, she finished her homework.

Why the Other Options are Incorrect?

Option 2: If, Although — Incorrect.

• "If" states a condition, but the delay really happened and the connection was really missed.
• "Although" is a conjunction and needs a full clause (Although we were delayed); "Although being delayed" is not standard.

Option 3: Although, Unless — Incorrect.

• "Although" shows contrast, but missing the connection is a result of the delay, not a contrast.
• "Unless" means "if not"; "Unless being delayed, we still had a good trip" makes no sense.

Option 4: After, Unless — Incorrect. The first word is right, but "Unless" (if not) gives no meaning in the second blank, which needs a word of contrast.
