4. 4. Which of the following BEST matches a central idea from the text with a detail that supports it?

• Central Idea:

  Many important discoveries are made during experiments. Supporting Detail: Doctors began using X-rays to examine injured patients.

• Central Idea: Some important discoveries are not well understood at first.

  Supporting Detail: Artificial sweetener was based on a kind of coal tar.

• Central Idea: Some scientists make accidental discoveries that help people. Supporting Detail: Penicillin is still used in modern times to save lives.

• Central Idea: Dedicated scientists may accidentally become great inventors. Supporting Detail: Fleming used plates called petri dishes to grow bacteria.

6. 6. Which of the following BEST summarizes the article?

• Sticky notes, microwaves, and artificial sweeteners all have something in common. Each of these useful things was discovered by accident. The same is true of a number of other discoveries. including penicillin, X-rays, and vulcanized rubber.

• Many important scientific discoveries have been made by accident. These include the discoveries of penicillin, X-rays, and vulcanized rubber. In each case, the scientist making the discovery had the experience to see the usefulness in what others might have considered a mere "accident."

• Alexander Fleming may be the person who made the most important accidental discovery of all time. He was working in his lab when he noticed a type of bread mold that killed bacteria. This led to the invention of penicillin, an antibiotic that has saved countless lives.

• When a good scientist discovers something by accident, the discovery involves more than just luck. Microwaves, penicillin, and X-rays are all examples of useful things discovered by scientists who knew how to turn a mistake into something good. Their "lucky accidents" had more to do with hard work than good luck.
