Could you please check if these disconnected sentences are possible? Thank you, Writeacher.

1)Italy sided with Germany (aslo allied with Germany) and declared war on the Western Powers.
2) Can I replace Italy with "she"?
Example: Italy was invaded by the Allies in 1943.
3) Bomber raids ..... on London and other important cities. (I need a synonym for "continued")
4) Margaret Thatcher limited Trade Union power.
The Suffragettes campaigned for recognition for women's right to vote.
5) He tries to justify her behaviour by saying that he didn't want to do her any harm.
6) She faints. When she comes to (also to herself?), the housekeeper is at her side.
7) She broke the door open/She broke open the door.

1)Italy sided with Germany and declared war on the Western Powers.

It's fine as is.

2) Can I replace Italy with "she"?
Example: Italy was invaded by the Allies in 1943.
Yes, you can do that if you wish.

3) Bomber raids ..... on London and other important cities. (I need a synonym for "continued")
The verb "persisted" should work.

4) Margaret Thatcher limited trade union power.
The suffragettes campaigned for recognition for women's right to vote.
Only if there's a formal group called Trade Union or a formal group called Suffragettes would you need capital letters there. Otherwise, these sentences are fine.

5) OK

6) She faints. When she comes to, the housekeeper is at her side.

7) She broke the door open/She broke open the door.
The second phrasing is better.

1) To check if these disconnected sentences are possible, you can analyze each sentence individually.

The first sentence, "Italy sided with Germany (also allied with Germany) and declared war on the Western Powers," is grammatically correct as it shows Italy's alliance with Germany and their declaration of war against the Western Powers.

2) As for the second question, if you want to replace "Italy" with "she" in the sentence "Italy was invaded by the Allies in 1943," the sentence would become "She was invaded by the Allies in 1943." It is grammatically correct to use "she" to refer to a female entity like Italy.

3) If you need a synonym for "continued" in the sentence "Bomber raids continued on London and other important cities," you could use "persisted," "prolonged," or "endured" instead. These words convey the idea of ongoing or uninterrupted bombardments.

4) The fourth and fifth sentences are disconnected, so I will address them separately.

For the sentence "Margaret Thatcher limited Trade Union power," it is grammatically correct and communicates that Margaret Thatcher took action to reduce the influence of Trade Unions.

The sentence "The Suffragettes campaigned for recognition for women's right to vote" is also grammatically correct and conveys the historical fact that the Suffragettes fought for women's right to vote.

5) The sentence "He tries to justify her behaviour by saying that he didn't want to do her any harm" is grammatically correct. It describes a person's attempt to defend or explain someone's behavior by mentioning that they did not intend to cause any harm.

6) In the sentence "She faints. When she comes to (also to herself?), the housekeeper is at her side," "to herself" can be added to clarify the meaning. So the revised sentence would be "She faints. When she comes to herself, the housekeeper is at her side." This implies that she regains consciousness.

7) The sentences "She broke the door open" and "She broke open the door" are both grammatically correct. They convey the idea that she exerted force to open the door forcefully or break it in the process.
