With this system, consumers view merchandise on a computer monitor and then use a modem, which links the computer to a telephone line, to signal the goods they want to order. Just as traveling salesman once brought wares to the home, electronic technology makes it possible for modern consumers to see and select from any array of goods in their homes.
7. The word “forecasting” is closest in meaning to:
D. decision making
8. The word “modem” refers to a type of:
A. electronic shopping
B. electronic device
D. computer screen
9. The word “wares” is closest in meaning to:
B. items for sale

Now Sony Electronics brings tomorrow’s technology to today’s home stereo. The same space-age circuitry used by the Wanderer spacecraft to send images of the most distant planets back to earth has been incorporated in the new Sony X-2700 stereo system. If your home entertainment is important to you, why settle for an old-fashioned stereo system when the Sony X-2700 is priced at only a few rupees more?

12. The argument above makes which of the following assumptions?
A. It is not possible to alter a significant current in world history merely by changing a single event
B. The technology necessary for time travel is likely to be developed in the near future
