LSAT Question Complete Explanation
This problem is a Must Be True (MBT) question, which means we need to find the answer choice that can be logically concluded from the information provided in the passage.
The passage tells us that caffeine can be as physically addictive as other psychoactive substances. Some people experience symptoms such as depression, drowsiness, or irritability when they don't have their usual dose of caffeine. The passage also states that as many people consume caffeine as consume any other addictive psychoactive substance.
Let's consider an example to make this more relatable. Imagine there are two types of candies: one with caffeine (Candy A) and one with another psychoactive substance (Candy B). The passage tells us that as many people consume Candy A as consume Candy B. Now, let's analyze the answer choices.
Answer choice (A): This choice talks about the number of people addicted to caffeine compared to other psychoactive substances. The passage only discusses the consumption of caffeine, not addiction rates. Therefore, we cannot conclude this statement.
Answer choice (B): The passage only provides information about symptoms related to caffeine withdrawal. It doesn't provide enough information to conclude that a physical addiction to any psychoactive substance will typically give rise to diverse psychological symptoms.
Answer choice (C): This choice discusses substances that are not psychoactive. Since the passage only talks about psychoactive substances, we cannot conclude anything about non-psychoactive substances.
Answer choice (D): The passage only states that some people experience depression, drowsiness, or irritability when they don't have their usual dose of caffeine. We cannot generalize this to all psychoactive substances and all people.
Answer choice (E): This is the correct answer. If alcohol is a physically addictive psychoactive substance, then we know from the passage that as many people consume caffeine as consume any other addictive psychoactive substance. Therefore, there cannot be more people who consume alcohol than consume caffeine.
In summary, the correct answer is (E) because it logically follows from the information provided in the passage.
