Oh wait, it could also refer to "the last 'word' in this line", so you would need to underline "word".
If it was this, there would be quotes around "word".
> No, wait, you needed to underline every occurrence of the word "line".
If it was this, it wouldn't say "last".
This particular one is not ambiguous.
Things like this were at the heart of what Jim Crow was in America. Selective and capricious enforcement of the law to disenfranchise and disadvantage black people at best, enable unaccountable violence against them at the worst.
As the judge of this test, I interpret your answer as incorrect. I expected the phrase, "the last word in this line" to be underlined. Test failed, no cheating required.
(Note that had you underlined the phrase, "the last word in this line", I would have still judged it incorrect, claiming that "word" or "line" should be underlined. Again, this requires no cheating.)
And who would you argue this to? The guy giving you the test who has the freedom to fail you for any reason they want?
There's no appeals court. These tests were not tests.
If there were quotes around those 6 words, it would make the question unambiguous, sure. But without the quotes, my interpretation and judgement is still valid.
> The quotes are needed to change this sentence from its clear meaning to these other ones.
Actually, they are optional for that purpose, not required. Without them, the meaning is ambiguous. Just as you claim your interpretation is the "clear meaning", others have exactly as valid a claim to their interpretation being the "clear meaning".
