Here are our test instructions:
1) If you see to / with, both prepositions may be correct.
For example, I am going to talk .... your sister.
a. to b. with / of c. to / with
Variant C is correct, because you can say 'to talk to somebody' and 'to talk with somebody'.
2) If all the answers in a test are correct, you will see a part of the main picture.
3) If less than half of the answers are correct, a cell will turn red and you will not see a part of the picture.
4) If more than half of the answers are correct and there are some mistakes, a cell will turn yellow and you will not see a part of the picture.
