The correct answer is: B. Extort : Obtain
Plagiarism is the act of taking someone else’s work or ideas and passing them off as your own. Borrowing is the act of taking something from someone else for a short period of time with the intention of returning it. Extortion is the act of obtaining something by force or threats. Obtaining is the act of getting something.
In the original pair of words, plagiarism is a type of borrowing. In the same way, extortion is a type of obtaining.
The other options do not have the same relationship as the original pair of words.
- Purify and filter are not the same thing. Purifying something means making it clean or pure. Filtering something means removing unwanted substances from it.
- Explode and ignite are not the same thing. Exploding something means causing it to burst violently. Igniting something means setting it on fire.
- Pilfer and steal are not the same thing. Pilfering something means stealing it in small amounts. Stealing something means taking it without permission.
