Rise or Raise?
Which verb should be used?

"Rise" means "to move up" or "to increase". It is an irregular verb. Its forms are:
rise - rose - risen - rising. The verb never takes an object, so you cannot say "to rise something". You can only say that "something rises".
Example sentences:
The number of unemployed has risen dramatically.
Prices have been rising faster than incomes.
The sun rises and sets every day.

"Raise" means "to lift somethnig" or "to increase something". It is a regular verb. Its forms are:
raise - raised - raised - raising. The verb always takes an object because you need to mention the thing that is raised by someone or something.
Example sentences:
I'm afraid we have to raise the debt limit.
Please raise your hands when you want to say something.
She raised her eyebrows in surprise.

Remember that the irregular verb "rise" is intransitive and cannot be used in the passive. So it is wrong to say that "something is / has been / was risen", but you can say that "something is / has been / was raised".
Compare the sentences:
Prices rise every year. Prices are raised every year.
The temperature rose to 30 degrees. The temperature was raised to 30 degrees.
You have to raise the standards. The standards have to be raised.
