Is there some kind of technology that would turn a rocket around 180 degrees? either that or take control of a guided rocket?

There is no (as far as I know) way to turn a rocket you're not in control of using mechanical methods. The best way would be (if it's a heat seeking missile for instance) to use flares to lure it somewhere else.

If the rocket is controlled by a computer, it is hypothetically possible to take control of the rocket; however, because of the security, this is about as hard as trying to finding the key of some well encrypted message : it's nearly impossible.

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
