7. consider a user who needs to transmit 1.5 gigabytes of data to a server. the user lives in a small town where only dial-up access is available. a bus visits the small town once a day from the closest city, located 150 km away, and stops in front of the user’s house. the bus has a 100-mbps wifi connection. it can collect data from users in rural areas and transfer them to the internet through a 1 gbps link once it gets back to the city. suppose the average speed of the bus is 60 km/h. what is the fastest way the user can transfer the data to the server?

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 !
