Look at gap 1: “rising ________” — what rises because of cars? Pollution! So pollution levels fits here.

Second paragraph:
> Whatever the 3. ____________ is, it has usually got four 4. ____________ and a gasoline or diesel 5. ____________ engine.

Gap 3: “Whatever the ________ is” — referring back to the subject, which is “motor vehicle”. But wait — “motor vehicle” is already used in the first sentence. Let’s check the list again. Actually, “motor vehicle” is in the box, and this sentence starts with “Whatever the...”, so it’s talking about any kind of motor vehicle. So motor vehicle fits here.

Gap 4: “four ________” — cars have four wheels → wheels

Gap 5: “gasoline or diesel ________ engine” — type of engine → internal combustion

So:

4. wheels
5. internal combustion

Gap 7: “transformed into ________” — exhaust fumes turn into bad air → poisonous smog

So:
6. exhaust fumes
7. poisonous smog
