So let's start by looking at how the question is written 4 as it is now, the program employed light detection and ranging technology, 5 and which uses lasers from satellites to measure distance to earth 6 and induce highly accurate topographical maps. 7 And so we should catch your eye. Here is the, 8 and which, right? We know that if we're separating two independent clauses 9 to complete sentences, we can use a comet. 10 And, but when you add a which here, 11 it makes that second part, that second part of our sentence, 12 a dependent clause.

Um, but you can also use it to separate two independent clauses. 19 So let's take a look. If it says that uses later lasers for satellites 20 to measure distances to earth and induce topographical maps, 21 is that an independent clause? Like we need it to be, 22 and the answer is no, it's a lacking a subject because we don't know 23 what is using, 24 um, the lasers from the satellites. 25 It's just says that uses lasers. 26 So our question is, what is that? So B doesn't work because it lacks 27 t...
