Answer:
1 d (just "promotion" is a noun, and has to be written "Promotion").
2 d (just "gewinn" is a noun, and has to be written "Gewinn". the same for "manager" : "Manager")
3 b (it depends on the type of sentence. for a regular explaining or telling sentence it is like in English
"I build a house" = "ich baue ein Haus". the verb is in the second meaningful position)
4 a. (again, similar to English. just the question in English starts with a helping verb like "are" or "is", while in German it also starts with the main verb)
5 d (I assume they mean the combination of helping verb and PPP of a verb to express present perfect like "ich habe meine Hausuebung gemacht" = " I have finished my homework).
6 a (the right German order would be "the workers came late to work)
7 c (the right German order would be 7a)
