Clarinet is a pair is made up of a woodwind instrument and a string instrument
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.
There are many kinds (can't name them all off the top of my head)
1. Telling someone you'll keep it a secret and then tell anyway...
2. Always being there for someone and then not
3. When you cheat on your husband/wife or someone you're in a relationship with
4. Using someone just to get some
Those are all I can think of (at the moment). But you can just pick whichever one you want.
