Stimulus

When drivers are deprived of sleep there are definite behavioral changes, such as slower responses to stimuli and a reduced ability to concentrate, but people’s self-awareness of these changes is poor. Most drivers think about to fall asleep, but they cannot.

    People who have been drinking alcohol are not good judges of whether they are too

    Just as drivers are bad judges of whether their sleep deprivation is making them a less safe driver, so too are people who are drinking alcohol bad judges of whether their alcohol consumption is making them a less safe driver.

  2. Correct84% picked this

    Elementary school students who dislike arithmetic are not good judges of whether multiplication tables should be included

    Why this is right

    This still retains the feature of "X being a bad judge of Y". However, it's less similar to the prompt than the other answers are because in this one there's no element of danger / possible bodily harm. ORIGINAL: you might fall asleep and crash A) you might drunk drive and crash C) you might keep working with heavy machinery while lightheaded from the fumes and cut off a limb D) you might walk out of a bloodmobile and pass out onto the concrete E) you might give up your schizophrenia meds and then be a danger to yourself and others This answer only involves the damage of not having multiplication tables in the school curriculum. Also, all the other examples are about "not being a good judge of your own body". This one is about not being a good judge of the school's curricular needs.

    Skill tested: Principle-Conform · how this choice captures the argument's function is the move to repeat next time.

    Just as drivers are bad judges of whether their sleep deprivation is making them a less safe driver, so too are factory workers a bad judge of whether noxious fumes are making them an unsafe worker.

    Just as drivers are bad judges of whether their sleep deprivation is making them a less safe driver, so too are blood donors a bad judge of whether their own lightheadedness makes them an unsafe walker.

  5. Matches3% picked this

    People who are being treated for schizophrenia are not good judges of whether they should

    Just as drivers are bad judges of whether their sleep deprivation is making them a less safe driver, so too are schizophrenics a bad judge of whether giving up their medical treatments would make them a less safe person. This one is definitely the weirdest of the four matches. The relationship drifts a little, but the principle remains of, "YOU are not the best judge of whether you're making a safe decision for yourself".
