Illogical Comparisons The Weirdest Topic on SAT Writing

Illogical Comparisons The Weirdest Topic on SAT Writing SAT / ACT Prep Online Guides and Tips Oftentimes, if I make an outlandish comparison, someone will turn to me and say, "You can't compare apples and oranges, Alex." Grammatically speaking, however, you absolutely can compare apples and oranges- they're both fruits! However,it's true that some comparisons are nonsensical, like a comparison between apples and eating apples. This kind of construction is called an illogical comparison, and it's one of the most unusual concepts on SAT Writing. Though essentially simple to spot, illogical comparisons are unfamiliar for most students becausethey rarely come up elsewhere. Feature image credit:MicroAssist/Flickr You Can Only Compare Equivalent Things An illogical comparison occurs when a sentence compares two things that aren't of the same type: Jimmy’s restaurant has more customers than Bob does. Even though it might seem fine, this sentence is comparing "Jimmy's restaurant"with "Bob," which makes no sense. In order to correct it, we have to alter the wordingso that the two things being compared are the same type of thing: Jimmy’s restaurant has more customers than Bob's restaurant does. This sentence, though correct, sounds pretty repetitive. To streamline it, we can drop the second "restaurant": Jimmy’s restaurant has more customers than Bob's does. It's still clear that we're comparing Jimmy and Bob's restaurants, but in a way that's not as redundant sounding. Depending on the sentence's construction, it mayalso be correct to substitute "that" or "those" for the second noun (as long as it's the same as the first one): I prefer the novels of J.K. Rowling to those of Stephenie Meyer. ("Those" takes the place of "the novels.") Though they look the same on most maps, the sizeof Alaska is actually twice that of Texas. ("That" takes the place of "the size.") There are two main types of illogical comparison errors that appear on the SAT writing: comparisons between people and things and comparisons between The first key rule is that you must compare people to people and things to things. So to return to our first example, it's correct to compare Bob's restaurant and Jimmy's restaurant because they're both things or to compare Bob and Jimmy because they're both people but you can't compare Jimmy's restaurant and Bob or Bob's restaurant and Jimmy. The second rule is that you can't compare something of specific type to all things of that type. This rule may sound strange, but it doesn't make sense to compare one person with everyone- you would compare them with everyone else. You can't compare something with a group that includes that thing without specifying that you're talking about everything else in the group. Let's look at an example: Incorrect: A cheetah is faster than any land mammal. Correct:A cheetah is faster than any other land mammal. Although most illogical comparisons questions on the SAT test one of these rules, you may see some that don't. In those cases, you'll have to use common sense to determine if a comparison is logical. For example, it makes sense to compare a train and a car, it doesn't make sense to compare a train and the length of a car. Pay attention to exactly what the sentence is saying- it's easy to extrapolate the intendedpointand miss the error in the wording. Keep this SAT writing strategy in mind! You can compare authors to authors and books to books but not books to authors.

Luckily, illogical comparisons generally appear in very similar ways, sothere are just a couple of clues that you need to watch outfor because they will often signal a comparison issue: Comparison key words- the words "like," "unlike," "as," and especially "than" almost always indicate a comparison and thus the chance for an illogicalone Full names- this is a slightly weird point, but if a question includes the full name of a person it often involves an illogical comparison. These names usually belong toartists or writers, and the sentence will set up a faulty equivalencebetween the individual and her work. Practicelooking for these clues on every SAT writing question until it becomes second nature. Identifying Sentence Errors Unlike most of the grammatical issues that show up in Identifying Sentence Errors (ISE) questions, illogical comparisons are hard to spot by just checking underlined words. Instead, as I mentioned above, you’ll need to keep an eye out for words that signal a comparison (like/unlike, as, than) and full names of individuals. If you see a comparison that you think might be faulty there are threesteps you need to take: Check for underlined nouns. Generally speaking, if there is an illogical comparison, one of the mismatched nouns will be underlined. Determine what the comparison is between. What two things isthe sentence, as written, comparing? Circle the nouns in the text. Decide whether the two things are equivalent. Is there a person vs. thing conflict? Are the two words being compared not equivalent in some other way? Let’s go through this process on a real SAT question: As with all ISE questions, the first step is to read the sentence. In this case, you should notice the clues "writer Sigrid Undset" and "like," which indicate that there may be an incorrect comparison. Are there any underlined nouns? Yes, both C and D include a noun. It's not immediately obvious which is involved in a comparison, so let's move on. What is being compared? Nowthe questions gets a bit trickier- the first part of the sentence, "Norwegian writer Sigrid Undset is like the novelist Sir Walter Scott," includes a comparison, but neither of our two underlined nouns. Plus, it's definitely correct, since it compares two people. However, there's another comparison in this sentence, "unlike his books," which does include an underlined phrase. So what's being compared with "his books"? "Unlike his books" is a modifier describing "she," which refers to Sigrid Undset. Are the two things equivalent?The comparison is between Sigrid Undset, a person, and SirWalter Scott'sbooks, things, so this is an illogical comparison. C is the correct answer- "his books" should be replaced with "him." This is an especially tricky question because of itscomplicated sentence structure (C is actually a faulty modifier as well), but following these steps will allow you to break down even the most complicated constructions. Let's move on to illogical comparisons in Improving Sentences. Improving Sentences Illogical comparisons appear in much the same way in Improving Sentences as they do in ISE, so you'll need to keep an eye out for the same clues: full names of people and comparison words. Once you've determined that there's likely an illogical comparison, follow these steps: Understand the error. The first step is to determine, what, if anything, is wrong with the comparison. Why are the two items being compared not equivalent? Rememberthat the most common issues are comparing people to things and something to all things of its type. Rule out answers that make the same mistake. Once you understand why the comparison is illogical, you can rule out all the answers that don't fix the problem. Pick between remaining choices.If there's more than one answer left, choose between the remaining answers. Watch for extra words that make the sentence ungrammatical and issues with plural vs. singular. This process may seem confusing, but it's actually quite simple in practice. Let's try it out on an official SAT question: After reading the sentence, you should notice the clue word "than," which indicates that this likely an illogical comparisons question. What, if anything, is wrong with the comparison?The sentence is comparing "the mass of its tiny body" with "humans." This is an illogical comparison- you can't equate the mass of something with a human. Thecomparison should be between the mass of an insect and the mass of a human.We can eliminateA. Rule out answers that make the same mistake.Answer choices C and D contain the same error: C merelytweaks the word order and D replaces the singular "human" with the plural "humans," which is actually even more wrong since the comparison is with a singular insect's body mass. Answer E seems to fix the problem by adding "body," but it's still not correct to compare a human body with the mass of an insect body. Pick between the remaining choices. The only answer that's left is B, which correctly compares "the mass of its tiny body" and "that of a human's body." B is the right answer. Comparing the size of an Allosaurus and the size of a human makes sense!

Clues to watch for: Comparative constructions: than, as, like/unlike Full names, especially of artists and authors Underlined nouns Key rules: Comparisons must be between equivalent things Compare people to people and things to things Don't compare something to a group it's part of SAT writing strategies: Practice watching for the clues and checking whethercomparisons are illogical. This type of error is initially difficult to spot, but once you've gotten familiar withthem, they tend to jump out at you. When dealing with illogical comparisons, don’t assume shortest is best. Though this rule often works for other types of errors, for these questions it will almost always give you the wrong answer. Remember that "that" is singular and "those" is plural.
