Explanation for Question 24 From the Writing Section on the Official Sat Practice Test 3

Now looking at the sentence for question 24, 2 it says one of CP works by eliminating fresh fruit productions of ethylene. 3 It is a chemical that causes fruit to ripen and eventually rot. 4 And so this is really a definition of ethylene, 5 right? The chemical that causes fruit to rot. 6 And we should notice that we have a comma. 7 And what comes before the Kala is an independent clause. 8 One MCP being our subject works, 9 being our verb. Um, and it's a complete thought. 10 Then we have a comma and as it's written, 11 we have another independent clause and this is not allowed. 12 The way it's written is what we call a comma splice. 13 You actually need a conjunction with your comma, 14 which is missing here. And so a is grammatically incorrect because it has an 15 independent clause. And C does the same thing. 16 When you say that is a chemical that causes fruit to ripen. 17 Eventually rot is also an independent clause. And so now the question is, 18 do we want it to say being a chemical or a chemical? 19 And so if you read the sentence, perhaps this is one you can just 20 do by intuition, right? One MCP works by limiting the production of ethylene, 21 a chemical that causes fruit to ripen. It should make sense to not have 22 the being here, because if you said being a chemical that causes a fruit 23 to ripen, that means that you're saying ethylene is being a chemical, 24 um, rather than just is a chemical, 25 right? There's no need to use ING verb here because ethylene is always a 26 chemical, um, that causes the fruit to ripen. 27 We wouldn't say it's being a chemical. And so with that in mind, 28 our best answer is going to be to delete because when we delete it, 29 we get an, a dependent clause rather than an independent clause, 30 which is what we want. And we also are just giving the definition of 31 ethylene right after we say what it is with a comma. 32 And so that's going to work really well. And we'll choose answer choice D.
