Its a modifying word, phrase or cause following a noun... Hope that helped :)
A rhyming couplet is two lines in a poem which rhyme and typically have the same meter, which means they have the same number of syllables.
The correct answer is D. "<span>Her breath in mine, our fluent dipping knives-/ Never closer the whole rest of our lives"
A and B don't even rhyme, and C belongs to a quatrain, not a couplet, and those two lines don't have the same meter. D meets all the requirements of a rhyming couplet. </span>
I am not too sure there is a clear answer to this question: in principle, you could hold a speech of 10 minutes on any topic, but the depth of the treatment of the topic would have to be adjusted.
I would choose answer C. the history of modern interior design: describing a history of anything requires a lot of details, and those need time.
Specifically, I find that options A and B are very easily condensed for 10 minutes: they are in any case not good options.
D. depends on whether this is just a general introduction or a very detailed, practically oriented, tutorial.
