Sure! I can help you check the grammar in the sentences you provided. Here are the revisions:

1) Female roles were performed/played/acted by boy actors.
- Explanation: Use the plural form "boy actors" instead of "boy-actor" to match with the plural noun "roles." The choice between "performed," "played," or "acted" depends on the specific context.

2) The apron stage was roofed and raised about five feet off the ground.
- Explanation: Remove the second "was" to make the sentence clearer and more concise. "Roofed" and "raised" are in past tense, indicating completed actions.

3) Most of the action took place there. The upper stage was used like a balcony. Correction: It was used to represent balcony scenes.
- Explanation: No grammar errors. The addition of "Correction:" clarifies the purpose of the revision and makes the sentence easier to follow.

4) Elizabeth I defended England against its enemies. She encouraged piracy against Spanish ships.
- Explanation: "Defeated" has been changed to "defended" to better convey the intended meaning. Elizabeth I defended England, not defeated it, from its enemies. The second sentence remains the same.

5) The E. theatre was a wooden structure, circular or octagonal in shape, with three tiers of roofed galleries.
- Explanation: Add a comma after "shape" to separate the two descriptive phrases. "Tiers" should be pluralized to match "three." The rest of the sentence remains the same.

I hope this helps! Let me know if you have any more questions or need further clarification.
