________ a synthetic opiate that blocks the effects of heroin and eliminates withdrawal symptoms, has a proven record of success for people addicted to heroin.

A. Methadone
B. Codeine
C. Morphine
D. Tetracycline
C?

A. METHADONE

C is wrong. Martin, look up the words you do not know, or read your text materials. Stop guessing, and don't rely on other students to help you cheat your way to a grade. The object here is for you to learn something about the world you live in, not just get a grade so you can go back to games or whatever you find more important than the world outside your immediate gratification and fun.

im sorry Reed but I've read my text book but i'm trying to check if there right or wrong and in this case it was wrong.

Calm the hell down Reed. It's obvious you're a grumpy 67 year old who couldn't do this yourself as a kid and now your kisses off. Get outta here.

The correct answer is A. Methadone.

Methadone is a synthetic opiate that works by binding to the same receptors in the brain that heroin does, effectively blocking the effects of heroin. It also helps to minimize or even eliminate the withdrawal symptoms that occur when someone stops using heroin.

To arrive at this answer, you could have eliminated options B (Codeine), C (Morphine), and D (Tetracycline) because they are not typically used as treatments for heroin addiction.

If you are unsure about the answer, it's always a good idea to do some additional research to confirm.
