Well, let's see... I don't know what a coordinating conjunction is off the top of my head, but I know B isn't the answer, since 'independent' means 'highly capable of handling oneself'. C <em>certainly</em> isn't the answer, simply because you can see by this answer they obviously do combine with a dependent clause from time to time. That leaves us with D and A, which both leave the same term. However, I do believe I can use the word preceding <em>conjunction</em>, which is <em>coordinating</em>, to realize that 'and,' 'but,' and 'or' are coordinating conjunctions. Seriously, D cannot be the answer because not every sentence starts with any of those. So your answer is A.
Juliet is too young and not ready to be married for another two years is the correct answer
Part A: Love is grander and more enduring than what it is often compared to.
Part B: "Shall I compare thee to a summer's day? / Thou art more lovely and more temperate."
