<p>For example:</p>
<p>"Delivering pizza, editing my high school newspaper, babysitting my nephew, and doing my homework leave (instead of 'leaves') me scarcely any free time."</p>
<p>I'm getting confused because I've seen a CB explanation for 2 gerunds acting as a singular subject instead of a plural one. I can't remember which question, and I could have remembered incorrectly.</p>
<p>Another example,</p>
<p>I can see that "Skiing on the snow tops, baking a cake, and watching TV are my some of favorite activities" would have to be plural. </p>
<p>Could anyone clear up the confusion?</p>
<p>Thanks</p>
<p>Most are plural, but some go together, like “drinking and driving is unsafe.”</p>
<p>Drinking and driving <em>is</em> fun.
Skiing and snowboarding <em>are</em> fun.</p>
<p>If the compound subjects that are both singular are joined by ‘or’, '‘either/or’ or ‘neither/nor’ the verb is singular. ‘Neither Jim nor Ed is chairman.’ ‘Either Jim or Ed is chairman.’ If the number of the compound subject is mixed, and they are joined by the conjunctions listed above, then the number of the closest one to the verb is usually the one than determines the verb’s number. Either Nancy or her sisters are going.</p>
<p>Since gerunds are singular, only the first situation applies.</p>
