When police pull over a driver suspected of operating a vehicle while

Official Explanation

If the answer choices are supported by the argument, this must be an inference question. Read the argument to get the lay of the land, but don’t break it down to a premise and conclusion. Instead, after you read the argument, look at each answer choice and see if there is any evidence in the passage to support that choice.

Choice A discusses the sentences a driver may receive. Although this answer could be true, the passage does not support it, so it must be eliminated.

Choice D goes too far; the passage states that officers “often” request a test, but this is not the same as saying they always request it. The validity of the test is not discussed, so choice C is out of scope.

Choice B also goes too far. There is nothing in the passage to indicate that any driver pulled over will be charged. The driver could pass the test or the officer could decide not to administer it and let the driver off with a warning. Either way, this choice is incorrect.

That leaves choice E, which is a valid inference. The argument says that in many states, refusal to submit is a crime. Thus, a driver with a blood alcohol level above the legal limit may be charged whether he submits (and is found to have a level above the limit) or refuses (and is charged with refusing a breathalyzer). Note that the answer doesn’t say the driver definitely will be charged, which is not a proper conclusion from the facts given.
