Thank you for your last suggestions

Can you tell me if the following statements are all possible?

1) Antony stirs the crowd against Brutus
2) He turns the crowd against him
3) He urges/incites the crowd to mutiny against him
4) Is this sentence still wrong?
If someone broke God's laws, many would suffer but in the end the guilty party would be punished and order
would be restored.
5) The grains group contain iron (or contains?) iron
6) Out of revenge (is it correct) she poured the milkshake over him
7) Mickey and Storm work as waiters (is waiters correct?)

1 and 2 are fine IF you put periods at the end!!

In 3, either word works; put a period at the end.

4 = If someone broke God's laws, many would suffer, but in the end, the guilty party would be punished and order would be restored.

In 5, "contains" because the subject is singular. And what belongs at the end?

6 is fine, but put a comma after "revenge." And what belongs at the end?

7 is fine -- what belongs at the end?

Sure! Let's go through each statement and address it individually:

1) Antony stirs the crowd against Brutus:
Yes, this statement is possible. Antony is influencing or provoking the crowd to turn against Brutus.

2) He turns the crowd against him:
This statement is possible as well. "He" refers to someone who is causing the crowd to shift their support or allegiance away from himself.

3) He urges/incites the crowd to mutiny against him:
Both "urges" and "incites" are possible verbs in this context. So, the statement is possible. It means that "he" is encouraging or provoking the crowd to rebel or rise up against himself.

4) Is this sentence still wrong? If someone broke God's laws, many would suffer but in the end the guilty party would be punished and order would be restored:
No, the sentence is grammatically correct. It suggests that if someone were to violate God's laws, it would result in suffering for many people. Eventually, the guilty party would be punished, and things would return to a state of order.

5) The grains group contain iron (or contains?) iron:
The correct form would be "contains" since "grains group" is singular. So, the correct statement would be: "The grains group contains iron."

6) Out of revenge (is it correct) she poured the milkshake over him:
Yes, this statement is correct. It describes an act of pouring a milkshake over someone as an act of revenge.

7) Mickey and Storm work as waiters (is waiters correct?):
The correct form would be "waiters" since there are multiple individuals working in the occupation of waiters. So, the correct statement would be: "Mickey and Storm work as waiters."
