<p>In the early days of American animation, most shorts were produced in New York City. From the Fleischer brothers’ studio came Betty Boop, Sullivan Studio produced Felix the Cat, and Aesop Fables Studio produced a series of shorts featuring the farmer Al Falfa. These studios churned out shorts at an astonishing pace that sometimes reached one new, though low-quality short per week.</p>
<p>F. No change
G. new, low-quality,
H. new, though, low-quality
J. new, though low-quality,</p>
<p>Error starts with new and ends with quality</p>
<p>The main reason choice G is incorrect because of the second comma: “short” is a noun, not another adjective. You could write “one new, low-quality short per week.” Putting an extra comma AFTER the last adjective in a series is a common mistake.</p>
