Europa has long been considered far too cold to support life, and with<\/span> 60 square miles of water thought to be frozen from top to bottom.<\/p>\n\u201c(A) Europa has long been considered far too cold to support life, and with<\/p>\n
\u201c(B) Europa has long been considered far too cold to support life, its<\/p>\n
\u201c(C) Europa has long been considered as far too cold to support life and has<\/p>\n
\u201c(D) Europa, long considered as far too cold to support life, and its<\/p>\n
\u201c(E) Europa, long considered to be far too cold to support life, and to have\u201d<\/p>\n
The First Glance does help on this one, but only if you have studied sentence structure explicitly. Before I did so, I used to think: \u201cOh, they started with Europa because they added a comma in some answers, but that doesn\u2019t really tell me anything.\u201d<\/p>\n
But I\u2019ve learned better! What is that comma replacing? Check it out: the first three answers all have a verb following Europa. The final two don\u2019t; that is, the verb disappears. That immediately makes me suspect sentence structure, because a sentence does have to have a verb. If you remove the main verb from one location, you have to put one in someplace else. I\u2019ll be watching out for that when I read the sentence.<\/p>\n
And now it\u2019s time to do just that. As I read the sentence, I strip it down to what we call the \u201csentence core\u201d in my mind. It took me a long time to develop this skill. I\u2019ll show you the result, first, and then I\u2019ll tell you how I learned to do it.<\/p>\n
The \u201csentence core\u201d refers to the stuff that has to be there in order to have a complete sentence. Everything else is \u201cextra\u201d: it may be important later, but right now, I\u2019m ignoring it.<\/p>\n

<\/p>\n
I greyed out the portions that are not part of the core. How does the sentence look to you?<\/p>\n
Notice something weird: I didn\u2019t just strip it down to a completely correct sentence. There\u2019s something wrong with the core. In other words, the goal is not to create a correct sentence; rather, you\u2019re using certain rules to strip to the core even when that core is incorrect.<\/p>\n
Using this skill requires you to develop two abilities: the ability to tell what is core vs. extra and<\/em> the ability to keep things that are wrong, despite the fact that they\u2019ll make your core sound funny. The core of the sentence above is:<\/p>\nEuropa has long been considered too cold to support life, and.<\/p>\n
Clearly, that\u2019s not a good sentence! So why did I strip out what I stripped out, and yet leave that \u201ccomma and\u201d in there? Here was my thought process:<\/p>\n
\n\n\nText of sentence<\/strong><\/td>\nMy thoughts:<\/strong><\/td>\n<\/tr>\n\n| \u201cWith\u2026\u201d<\/td>\n | Preposition. Introduces a modifier. Can\u2019t be the core.<\/td>\n<\/tr>\n | \n\u201cWith<\/em> surface temperatures estimated<\/em> at<\/em> minus 230 degrees Fahrenheit,\u201d<\/td>\n| Each word I\u2019ve italicized introduces a new noun modifier. Nothing here is a subject or main verb. *<\/td>\n<\/tr>\n | \n| \u201cJupiter\u2019s moon Europa\u201d<\/td>\n | The main noun is Europa; ignore the earlier words.<\/td>\n<\/tr>\n | \n| \u201cEuropa has long been considered far too cold to support life,\u201d<\/td>\n | That\u2019s a complete sentence. Yay.<\/td>\n<\/tr>\n | \n| \u201c, and\u201d<\/td>\n | A complete sentence followed by \u201ccomma and\u201d? I\u2019m expecting another complete sentence to follow. **<\/td>\n<\/tr>\n | \n\u201cwith<\/em> 60 square miles of<\/em> water thought<\/em> to be frozen from<\/em> top to<\/em> bottom.\u201d<\/td>\n| Same deal as the beginning of the sentence! Each word I\u2019ve italicized introduces a new modifier. Nothing here that can function as a subject or main verb.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n \u00a0<\/p>\n * Why isn\u2019t estimated<\/em> a verb?<\/p>\nEstimated<\/em> is a past participle and can be part of a verb form, but you can\u2019t say \u201cTemperatures estimated at minus 230 degrees Fahrenheit.\u201d You\u2019d have to say \u201cTemperatures are<\/em> estimated at\u2026\u201d (Note: you could say \u201cShe estimated her commute to be 45 minutes from door to door.\u201d In other words, estimated<\/em> by itself can be the main verb of a sentence. In my example, though, the subject is actually doing the estimating. In the GMATPrep problem above, the temperatures<\/em> can\u2019t estimate anything!)<\/p>\n** Why is it that I expected another complete sentence to follow the \u201ccomma and\u201d?<\/p>\n The word and<\/em> is a parallelism marker; it signals that two parts of the sentence need to be made parallel. When you have one complete sentence, and you follow that with \u201ccomma and,\u201d you need to set up another complete sentence to be parallel to that first complete sentence.<\/p>\nFor example:<\/p>\n She studied all day, and she went to dinner with friends that night.<\/p>\n The portion before the and<\/em> is a complete sentence, as is the portion after the and<\/em>.<\/p>\n(Note: the word and<\/em> can connect other things besides two complete sentences. It can connect other segments of a sentence as well, such as: She likes to eat pizza, pasta, and steak<\/em>. In this case, although there is a \u201ccomma and\u201d in the sentence, the part before the comma is not a complete sentence by itself. Rather, it is the start of a list.)<\/p>\nOkay, so my core is:<\/p>\n Europa has long been considered too cold to support life, and.<\/p>\n And that\u2019s incorrect. Eliminate answer (A). Either that and<\/em> needs to go away or, if it stays, I need to have a second complete sentence. Since you know the sentence core is at issue here, check the cores using the other answer choices:<\/p>\n![\"modifier\"](\"\/\/www.manhattanprep.com\/gmat\/wp-content\/uploads\/sites\/18\/2014\/12\/modifier1-1024x223.png\") <\/p>\n
Here are the cores written out:<\/p>\n \u201c(B) Europa has long been considered too cold to support life.<\/p>\n \u201c(C) Europa has long been considered as too cold to support life and has 60 square miles of water.<\/p>\n \u201c(D) Europa and its 60 square miles of water.<\/p>\n \u201c(E) Europa.\u201d<\/p>\n (On the real test, you wouldn\u2019t have time to write that out, but you may want to in practice in order to build expertise with this technique.)<\/p>\n Answers (D) and (E) don\u2019t even have main verbs! Eliminate both. Answers (B) and (C) both contain complete sentences, but there\u2019s something else wrong with one of them. Did you spot it?<\/p>\n The correct idiom is consider X Y<\/em>: I consider her intelligent. There are some rare circumstances in which you can use consider as<\/em>, but on the GMAT, go with consider X Y<\/em>. Answers (C), (D), and (E) all use incorrect forms of the idiom.<\/p>\nAnswer (C) also loses some meaning. The second piece of information, about the water, is meant to emphasize the fact that the moon is very cold. When you separate the two pieces of information with an and<\/em>, however, they appear to be unrelated (except that they’re both facts about Europa): the moon is too cold to support life and, by the way, it also has a lot of frozen water. Still, that’s something of a judgment call; the idiom is definitive.<\/p>\nThe correct answer is (B).<\/p>\n Go get some practice with this and join me next time, when we\u2019ll try another GMATPrep problem<\/a> and talk about some additional aspects of this technique.<\/p>\nKey Takeaways: Strip the sentence to the Core<\/h3>\n(1) Generally, this is a process of elimination: you\u2019re removing the things that cannot be part of the core sentence. With rare exceptions, prepositional phrases typically aren\u2019t part of the core. I left the prepositional phrase of water<\/em> in answers (C) and (D) because 60 square miles<\/em> by itself doesn\u2019t make any sense. In any case, prepositional phrases never contain the subject of the sentence.<\/p>\n(2) Other non-core-sentence clues: phrases or clauses set off by two commas, relative pronouns such as which<\/em> and who<\/em>, comma + -ed or comma + ing modifiers, -ed or \u2013ing words that cannot function as the main verb (try them in a simple sentence with the same subject from the SC problem, as I did with temperatures estimated<\/em>\u2026)<\/p>\n(3) A complete sentence on the GMAT must have a subject and a working verb, at a minimum. You may have multiple subjects or working verbs. You could also have two complete sentences connected by a comma and conjunction (such as comma and) or a semi-colon. We\u2019ll talk about some additional complete sentence structures next time.<\/p>\n * GMATPrep\u00ae questions courtesy of the Graduate Management Admissions Council.
