<p>I don't understand why the answer to this problem is the has right after recently. Can someone please explain why the has is incorrect?</p>

<p>While the effect of disease-causing agents on cigarette smokes has been known for years, only recently HAS the damaging effects of cigarette smoke on second-hand smokers become widely recognized.</p>

<p>“Has” is always singular.
The second “has” is referring to the “damaging effects.”
“Damaging effects” is plural. </p>

<p>Switch the “has” to “have” and your golden :).</p>
