Riker wrote the poem "Spanish Dancer" in rhyme but also in German. When it was translated, it lost the rhyming words. So the correct answer is D.
The Central Idea is "The introduction of bicycles offered women relief from their oppressive restrictions." Hope it helps!
The correct answer is C. The first example cannot be correct because the colon simply doesn't fit there - a comma would fit better. The second one is also incorrect as you don't need to put a colon after every word, just once before the first word. The last example also doesn't need a colon, you can just enumerate these various states without the use of colon. So naturally, we are left with only one option, and that is C.
