Answer: both safe and effective.
Explanation:
In 1962, there was a drug in Europe and Canada that was meant to treat morning sickness in pregnant women. The drug instead caused birth defects in many people.
The Federal government of the US decided that it would be best to take action against that drug and others like it from harming the U.S. like it did those other countries.
This action came in the form of the Kefauver-Harris amendment to the Federal Food, Drug and Cosmetic (FD&C) Act. According to this amendment, companies manufacturing drugs had to make sure that a drug was not only safe for consumption, but effective in treating what it is meant to treat as well.
1. Use your brain
Take breaks between homework and make sure you drink water in between breaks because that's how your brain refreshens. Also, be sure to think critically and don't just write down random stuff which will help you get past your homework. It's important to think through every step of the way in assignments and tests.
2. Use online webpages to help you
By this, I don't mean plagiarise because it violates one's academic integrity, but use the thesaurus to help you reword a phrase.
3. Read more
Reading can help you with writing because it's great to have a few more exemplars to guide you as you strengthen your writing path.
Good luck! This question wasn't that specific so sorry I couldn't narrow it down for you on what you specifically want to work on.
