I have always maintained that in relation to cats, eating makes them sleepy and sleepingmakes them hungry. This is almost always the case. Sometimes they are playful. If a cat is asleep, the only thing that will wake them up is if you call them to eat. Otherwise, they will ignore you. Once a cat eats, she can beplayful. When a cat is playful, she can either eat or sleep. If a cat is eating, it will eat more (but still ignore), play or go to sleep. Implement the three cat states: asleep, hungry, and playful. Define/implement the following cat methods: sleep(), eat(), play(), ignore()

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 !
