Final answer:
A period should appear outside a quotation mark when it is not part of the original quoted material.
Step-by-step explanation:
In English grammar, a period should appear outside a quotation mark when it is not part of the original quoted material. For example:
- The teacher asked, "Who is responsible for this?".
- I read the excerpt from the textbook: "Technology has transformed the way we communicate".
However, if the period is part of the original quoted text, it should be placed inside the quotation mark. For example:
- The famous saying goes, "All that glitters is not gold."
- The article stated, "According to the survey, 80% of students reported feeling stressed before exams."
