There are a few talking points here, but everything checks out. The adverbial to measure is simply a shortened form of in order to measure, and generate builds from the same understood to. Depending on the gap between the beginning of parts X and Y in this sort of and construct, you may see a word such as to repeated in front of the second element, but there is no definite rule (e.g., one based on word count) on when that needs to occur. Finally, the placement of the word likely allows us to appreciate that researchers can use these maps to check for probable volcanic floodplains (perhaps without having to risk life and limb by traveling to such locations). There is nothing that stands out as incorrect, so keep this one.
First off, notice that to has been swapped out for that at the head of the underlined portion. Although the nature of the clause is somewhat different from that of the earlier phrase, there is nothing inherently wrong with saying lasers from satellites that measure distances to Earth. In any case, I would not eliminate the answer choice on such grounds. The latter portion runs into trouble, though, when it comes to the meaning conveyed, and this meaning hinges on where likely falls. Whereas before, the maps helped researchers identify possible volcanic floodplains, now the maps are definitely of those floodplains, and, worse yet, likely assess makes it sound as if the maps are being generated for some unknown purpose, that maybe researchers will get around to checking out all these highly accurate maps, but maybe not. Even though there is nothing grammatically wrong with the sentence, the meaning is certainly not as clear as what was expressed in the original sentence, so I would discard this answer choice in favor of (A).
This likely keeps bouncing around and wreaking havoc on the meaning of the sentence. Now the nature of the satellites is more or less a complete mystery, the information pertaining to them speculative. Why, then, do we get this description about how the satellites work and what they apparently do? Something seems off when the sentence is considered as a whole. Also, even though measuring and generating are parallel, there is no compelling reason to opt out of our adverbial to phrase for this prepositional for phrase—using lasers to measure is the grown-up version of using lasers for measuring. This should be another easy elimination.
This version is a little to happy. But first, we once again have a problem with likely. This time, the measuring can be taken as fact, but the generating of maps is uncertain. Getting back to to, generate maps to researchers could work in a certain context, perhaps if the sentence wrapped up, on their mobile devices. We might picture a sentence that was outlining a process about the transmission of data. But in this sentence, maps to researchers to assess is difficult to follow; the preposition for is warranted: maps for researchers to assess. Since this is another subpar version of (A), we should feel comfortable tossing it aside.
Again, this one is fine grammatically. But now we are pigeonholing the type of researchers for whom these maps are generated. Evidently, not just any researchers can gain access to these maps, only those who are likely to assess volcanic floodplains. Do the satellites generate other types of maps for different researchers, perhaps less accurate maps? This is a subtle change of meaning, but if we have reason to doubt the sentence, we should not merely close our eyes and hope for the best. SC is about seeking to attack each of the five options, and clarity of meaning should be your primary concern. This iteration just misses the mark.
