Could you explain to me please why "loudly" does not suit? Or is "aloud" as well an adverb?

Both aloud and loudly are adverbs. Loudly means with great noise, in a very audible tone. Aloud simply means in a natural speaking voice. So, if you read a text you can read aloud, that means you can hear yourself. If you read a text loudly you use force and speak in a very loud voice.

Hehe, fortunetely I picked the answer by the pronunciation of "allowed" and "aloud". Thanks that I learned the real reason for the answer.
