Unit 2 DUA Review

Which claim in the passage is supported with examples?

• If you are cowed by the idea, you are not alone.

• A computer that took in so much data would run out of memory.

• Humans are also much better than computers at recognizing patterns.

• But you can adapt and explore new possibilities.

Part A: Which claim is most important to the author’s argument?

• Computers can calculate much faster than the human brain.

• Computers are even more powerful year after year.

• People are eager to accept the challenge of pitting their brains against computers.

• The human brain is much more complex and has a wider range of capabilities than a computer.

Part B: Which sentence from the text supports your answer in Part A?

• If you are cowed by the idea, you are not alone.

• In the 1980s, even the biggest computers in the world could not play expert chess or win at high-level quiz games.

• They can work through millions of calculations in a second.

• By one estimate, the brain can process about 100 million instructions per second (MIPS).

A central idea of the text is that people are smarter than computers because people

• possess a larger capacity for memory.

• can follow instructions more quickly.

• pay closer attention to what they do.

• have different kinds of mental abilities.

Which sentence from the text best supports the idea that people are more creative than computers?

• A computer, on the other hand, cannot solve a new problem unless a programmer has already told it how to go about solving it.

• Chess allows only a limited number of moves, although they can be put together in countless ways

• By one estimate, the brain can process about 100 million instructions per second (MIPS).

• They ask you to type the series correctly to prove that you are a real person and not a machine.

Which sentence from the text best expresses the author’s view of the human brain?

• Surely the evidence points to the superior brainpower of the machines.

• There is no question that computers can calculate much faster than humans.

• Now consider the marvel of the human brain.

• Although Kasparov was surely paying close attention to the chess game, only a fraction of his brain’s processing power was available for it.

Which is the central idea of the text?

• Computers cannot take in as much data as human brains can.

• People can recognize patterns, while computers generally cannot.

• Computers have developed to the point where they can win chess games against humans.

• Computers can do amazing things, but the human brain remains superior to them.

There is no question that computers can calculate much faster than

humans. They can work through millions of calculations in a second.

They can store, retrieve, and process vast amounts of information. They

are focused and accurate. Watson won at Jeopardy! by mining a

database of more than 200 million pages in less than three seconds.

Deep Blue was able to analyze billions of possible chess moves during

a single three-minute turn.

The phrase work through means the same as

• complete.

• study.

• correct.

• share.
