<p>please explain these two questions..</p>
<p>I put "a unique type of intelligence"
and "it is impossible to measure the intellegence level"</p>
<p>Well the text lists some activities that are very routine (things we do all the time). Thus, they have skills usually associated with humans.</p>
<p>As for your other question (number 10), the author argues that intelligence is merely different. From collegeboard: “The author of Passage 2 does not think that intelligence is a single uniform ability that different species happen to have in different amounts. Passage 2 suggests that there are different kinds of intelligence, and that the kind of intelligence a creature has is appropriate to that creature’s way of life.”</p>
<p>The last sentence of passage 2 affirms this in saying “all we can say is that dolphin intelligence is different”</p>
<p>A general rule to follow is to eliminate extreme answers. Number ten says that it is impossible to measure, and claiming that an intelligence is unique can also be seen as extreme.</p>
