Answer:
"she expressed<em> them </em>imperfectly”
Explanation:
The speaker is not complying with concord. Her reference is ,realised by <em>them</em>, ambiguous. <em>Them</em> lacks any reference if we move backwards in the excerpt. We may assume <em>them</em> refers to what she had to say,but <em>it</em> shoudl have been used , instead. However, <em>them</em> may refer to <em>thoughts</em> that comes later in the excerpt:"She expressed<em> them</em> imperfectly her thoughts were imperfect.", in these sentences ,which are not coherently linked , we infer that <em>them</em> is referring to <em>thoughts.</em>
The prehistoric reptiles known as dinosaurs arose during the Middle to Late Triassic Period of the Mesozoic Era, some 230 million years ago. They were members of a subclass ofreptiles called the archosaurs (“rulingreptiles”), a group that also includesbirds and crocodiles.
