[Video] Q18: No change or falls or will fall or had fallen

Explanation for Question 18 From the Writing Section on the Official Sat Practice Test 1

So for question number 18, we're still here this first sentence here of the 2 passage. And it says, according to box, 3 a leading Greenland expert Tundra fires in 2012, 4 from as far away as north America produced great amounts of some of which 5 drifted over Greenland and giant plumes of smoke and then fell as particles onto 6 the ice sheet. So we see here in our answer choices that we still 7 have the word, the verb to fall, but we have a bunch of different 8 tenses, right? Different ways of saying to fall. 9 And whenever you see that you're going to be choosing, 10 um, between different types of the same verb, 11 but different forms.

That's actually the only verb in that sentence, 18 but it says drift ed, which makes us know that we have to be 19 working with the past tense here. 20 So fall or fell is good. 21 Falls is not going to work.

And we don't. So that's why D is wrong. 28 And we're just going to go with the simple past tense. 29 So our best answer is a.
