Answer:
<em>The </em><em>nosy</em><em> visitors observed the lions' routine for nearly an hour before moving on.</em>
Explanation:
In this passage, we have a description of an average safari with a lot of tourists trying to capture the perfect photo, no matter what it takes. It is obvious that the lions are not a fan of it, as the people keep mingling around them, staring, making noise, etc, so it is almost like in a zoo. So, the author used the neutral word <em>curious</em>, while <em>nosy</em>, meaning <em>being too much into others` business</em>, is more suitable, but only if we want, like it is said, to create a more negative connotation.
