A person must contribute to the nation in a specific manner(doing something special) .
I would say the editing phase, as I have done a lot of writing and multiple people around me refer it as that, but the revising stage also covers editing, which doesn't make much sense. I guess that it depends on what your class taught you. Sorry if this doesn't help you, but my best answer would be the editing, since it covers going back through a paper to check for errors. Do you know what the exact definition of "editing" and "revising" is and could you get back to me with that?
Answer:
The sentence that shows the best placement for the modifier "that was on sale" is the following one: Sheila bought soap that was on sale at the farmer's market.
Explanation:
A relative clause is a subordinate clause which specifies or gives information about a person or thing. In this case, the relative clause, <em>that was on sale, </em>gives further information regarding the noun <em>soap.</em> What is more, this relative clause is considered essential because it provides necessary information with respect to the noun it refers. If it was dropped, the sentence would not have the same meaning (see 1).
1) Sheila bought soap at the farmer's market
Sheila bought a particular soap, the soap which was on sale, not any soap. With the information included in the relative clause, the reader can identify which soap Sheila bought.
