A scientist has been working for 15 years to develop a new type of plastic material, but she has not yet been successful. Which of the following best explains why her work is still a success?

New ideas often develop from unsuccessful experimentation.

b

The original problem was not solved and can now be abandoned.

с

Most scientists require several decades of experimenting before achieving their goals.

d

The scientist has demonstrated that there are no new plastics for scientists to develop.

Its proably A beacause thats how most scientists acheived their goals

a. New ideas often develop from unsuccessful experimentation.

Explanation:

The scientists' work would still be considered a success because new ideas often develop from unsuccessful experimentation. Many of today's famous inventions and celebrities failed at the start of their career. However, because they did not give up on their goal, they eventually succeeded. A few examples of those people are Bill Gates, Albert Einstein, and Michael Jordan.

Here is an influential quote, said by Michael Jordan, that I think accurately supports this topic of discussion:

"I've missed more than 9,000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game-winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."

the correct answer is:

a population changes in response to a change in the environment.

answer: 45
