<p>"Between 1903 and 1913, the British suffragettes, a group devoted to helping women win the right to vote, resorted to increasingly extreme measures to make their voices heard."</p>
<p>Is there anything wrong with this question? I think "their" is ambiguous but the author says it is correct.</p>
<p>The subject here is “british suffragettes”. It is defined as a group in the next 3 words. This means singular tense should be used. Making “their” incorrect. A group cannot make their voice heard. A group makes its voice heard</p>
<p>If “suffragettes” is taken as plural, then I think no error. “Increasingly” sounds a little funny but I can think of any replacement so we’re gonna have to assume its correct.</p>
<p>The subject is plural (suffragettes). The group part is in a clause separated by commas, which could be removed from the sentence. If you do that, the subject-verb agreement is clearer.</p>
<p>But that is so self-contradictory: the suffragettes = plural; the group = singular; the group modifies the suffragettes -> singular modifies plural?</p>
<p>The Washington Wizards are leading by 10 points.</p>
<p>The Washington Wizards is leading by 10 points.</p>
<p>Washington Wizards is a single team. However is defined to be plural. I dont know why I didnt pick that up before. Substitute like this if u are unsure about a subject or verb</p>
