<p>Undermine.</p>

<p>As in:</p>

<p>‘‘Which of the following, if true, would undermine the validity of the author’s assumption about the impact of mechanical clocks (’‘When the first…the laboratory’’) in lines 37-42?</p>

<p>I always get these kinds of questions wrong because I never know what ‘‘undermine’’ means. What does it mean?</p>

2

<p>Undermine (in the context of SAT passages) generally means to disqualify/to make the argument less valid.</p>

3

<p>undermine = to lessen the value of; degrade</p>
