Step-by-step explanation:
for exercise b) you are asked to match the terms listed in section a) to the terms in section b) so you get phrases, that make sense. Then you need to put the phrases in the suiting section. On the images you see hints for this.
Section 1 is situations in which you adress the other person informally (adult speaking to child). Section 2 is one person adressing a group of people and section 3 is a situation where you formally adress the other person (child speaking to adult).
I want to stress here, that image 3 is a little misleading because you adress another person formally when the other person is an authority (your boss at work for example) or when it's a stranger. It is not necessarily due to age. Children usually adress their parents with "du" and not "Sie" in this modern day and age. 100+ years ago, children, especially in upper class families, did adress their parents with "Sie" but those times are long gone :) Maybe the person on the image is just the teacher.
Also, there is a "mir" too much in section b), it only fits to "hilf" but it would be more common to add a polite please too. So not sure why they give 10 options in b) but only 9 in a).
Exercise 7:
You are asked to assign the phrases/reactions to the emotes (phrase relates to time issues or positive/negative meaning/connotation)
Exercise 8:
You are asked to build a sentence with the given pronouns and words using the imperative form of the verb.
