Answer Choices
Their young tend to hop along beside their parents instead of flying beside them.
Their method of locomotion is similar to that of ground birds.
They use the ground for feeding more often than for perching.
They do not use a flapping stroke to aid in climbing slopes.
Explanation for Question 29 From the Reading Section on the Official Sat Practice Test 3
Question 29 says what can reasonably be inferred about gliding animals from the passage? 2 So let's look back in the passage and see if we can find any 3 references to gliding animals so we can find exactly two. 4 So one comes in the little blurb before the passage. 5 It says the tree down theory assumes they were tree climbers that left and 6 glided among branches. So just one of the theories on how the ancestors 7 of birds evolved the ability to fly. So they're starting in trees and they're 8 gliding down. And then we find another reference to gliding 9 animals. In the last paragraph, it says with one fell swoop, 10 the dials came up with a viable origin for the flapping flight stroke of 11 birds, something gliding animals don't do. 12 And that's a shortcoming of the tree down theory and an aerodynamic function for 13 half formed wings. One of the main drawbacks to the ground up hypothesis. 14 So we see the reference to these gliding animals here. 15 And what they're seeing is that it's something 16 that gliding animals don't do being the flapping flight stroke. 17 So let's see which answer choice shows that gliding animals don't have a 18 flapping flight stroke. 19 So if we start with answer choice a, 20 it says they're young tend to hop along beside their parents instead of flying 21 beside them. So based on the information we saw in that paragraph 22 where the gliding animals don't do the flapping flight stroke, 23 you might be able to assume with several kind of levels ...
