Consider the following example: Although neurologists have long been aware of the importance of sleep for our well-being, they did not expect that sleeping more than nine hours a day, the amount of rest previously associated with a healthy lifestyle, would lead to a decrease in quality of life and an increase in depressive symptoms like sleeping less than six hours has. A. would lead to a decreasing quality of life and an increase in depressive symptoms like sleeping less than six hours has. B. will lead to a decreasing quality of life and increasing depressive symptoms as less than six hours of sleep have. C. would lead to a decrease in quality of life and an increase in depressive symptoms as does sleeping less than six hours. D. to lead to a decrease in quality of life and an increase of depressive symptoms like sleeping less than six hours does. E. leading to a decrease in quality of life and an increase in depressive symptoms, unlike sleeping less than six hours. The main challenge of this question might be connecting the underlined portion with the rest of the sentence. To see the core structure, you need to ignore the modifier that precedes the underlined part, focusing on they neurologists did not expect that sleeping more than nine hours would lead to certain changes. Neurologists expectations should be described with a verb in the future, but since they did not expect refers to the past, any answer choice that does not start with would lead is wrong. According to the original sentence, sleeping more than nine hours a day has two consequences, which must be described with parallel phrases: a decrease in quality of life and an increase in depressive symptoms ( NOT decreasing quality of life and increasing depressive symptoms.) A further mistake in the underlined portion is the incorrect adverb for comparison: the sentence intends to let us know that sleeping less than six hours leads to a decrease in quality of life, and that sleeping more than nine hours has the same consequences. Moreover, the verb has in like sleeping less than six hours has is wrong. It could have been used correctly in a phrase such as X has led to more serious consequences than Y has led to. It is, however, incorrect to say that X leads to more serious consequences than Y has led to. ![]() We have already looked at what makes Choice A the wrong answer. Now lets analyze the remaining choices and pick the right one. Choice B begins with will, whereas the correct choice should start with would. B also deceptively tries to make the consequences of too much sleep parallel ( decreasing quality of life and increasing depressive symptoms ), but sleeping does not lead to quality and symptoms; it leads to a decrease in the former and an increase in the latter. As less than six hours of sleep have is not parallel to sleeping more than nine hours. The verb have implies have led, but we cant change tenses in the middle of the sentence. ![]() It can be either they expected THAT sleeping would lead or they expected sleeping TO lead. In the original sentence, there expected is followed by that, so only the first variant can be correct. A further mistake is the use of the wrong preposition in an increase of depressive symptoms; it should be an increase in depressive symptoms. Finally, instead of like you should use as: as sleeping less than six hours does. Choice E contains a mistake similar to that in Dit violates the grammar rules in they expected that sleeping WOULD lead: instead, it uses they expected sleeping more than nine hours leading to a decrease, a phrase that does not make sense. ![]() To cope with questions like the one we have just examined, remember to watch out for multiple mistakes both in the original sentence and in the answers, check whether your choice fits with the rest of the sentence, and be attentive to changes in meaning.
