Answer:
If Passage 1 is adapted from "Ancient DNA Tells Story of Giant Eagle
Evolution," © 2005 by Public Library of Science, then the answer would be as follows:
It can reasonably be inferred from Passage 1 that, for most bird species, there is a certain size at which they
a. are unable to fly.
Explanation:
According to Passage 1, "When the dodo's ancestor (thought to be a migratory pigeon) settled on this island with abundant food, no competition from terrestrial mammals, and no predators, it could survive without flying, and thus was freed from the energetic and size constraints of flight.
"
"Size constraints of flight" means that the birds that are big to a certain size cannot/could not fly. Taking examples of some birds once roaming New Zealand into consideration, they were giant birds with large wingspans, and therefore, they were unable to fly (flightless).
Other options, namely b. require less energy when flying; c. are more likely to attack other animals; and d. do have a to compete with other birds for food, are nowhere found in Passage 1. In other words, No related information is available.
Therefore, the most possible answer is a.
The belief that the romantics held about humanity is that b) the humanity is at its best in nature.
They believed we should all return to nature and our previous behavior, because nature is inspiration, and it will help us regain our lost good qualities.
Answer:
A. reserved for another time
Explanation:
The phrase "left in midair" as used in the passage means that something was left undone and pending, waiting for when next it would be used.
According to the passage, a deal was uncompleted, and because of that, and because a compromise could not be reached, it was "left in midair" which means that it was reserved for another time.
