Join the following sentences to make one complete sentence without using and, but or so.
Rahul ran all the way to the bus stop. He missed the bus.
Topic: Synthesis — clause of concession
Answer
Although Rahul ran all the way to the bus stop, he missed the bus. (Also acceptable: In spite of running all the way to the bus stop, Rahul missed the bus.)
Contrast again — he ran AND YET missed it — so ALTHOUGH or IN SPITE OF.
This question is worth comparing with 5(c)(i) above, which has the same structure. Two of the four synthesis questions in this paper are contrast questions, which is typical: CONTRAST and REASON together account for most of them, and recognising which you are looking at is most of the work.
The signal for contrast is that the second sentence DEFEATS the expectation raised by the first. He ran, so you expect him to catch it; he did not. Wherever that pattern appears, the conjunction is although, though, even though, or in spite of.
