In this conversation, which group discussion technique does anna most clearly show?

jennifer: so, tell me about what you thought when he opened the door for the first time?

daniel: that was a weird moment. why open a door when you know you won't like what's on the other side?

anna: i get that. but people are curious. they need to know. for me, that was the point. he had to know what was on the other side, even if it terrified him. it was all part of the symbolism

a. challenging ideas
b. using evidence to support opinions
c. outlining a discussion plan
d. identifying bias

The correct answer is A. Challenging ideas

Explanation:

In a discussion, challenging ideas imply that as a participant you question ideas or beliefs assumed and instead you look for alternative proposals that allow understanding the issue discussed differently. In the case presented, Anna shows the use of challenging ideas technique because she is questioning the idea purposed by Daniel "That was a weird moment. Why open a door when you know you won't like what's on the other side?", and instead she looks for an alternative explanation by focusing on the idea human beings are curious and therefore it should not be assumed the character acted irrationally or weirdly. Thus, the technique Anna most clearly shows is Challenging ideas.

the boy's acceleration toward the girl is 2.08 m/s^2.

explanation:

according the newton's third law, the force causing the girl accelerate towards the boy will be me with equal counter-force causing the boy to accelerate towards the girl. these forces will be of equal magnitude and allows us to determine the boy's acceleration:

the boy's acceleration toward the girl is 2.08 m/s^2.
