Check 3 of my sign language questions : )
1. to sign a comparative adjective in asl, you would add the sign for the suffix -er after the descriptive word is signed.
true
false
2. what is a classifier in asl?
a. signs that are used to show ownership or possession
b. signs that are used to represent general categories or classes of things
c. signs that are used to replace state of being verbs
3. to indicate possession, what should your handshape be?
a. "s" handshape
b. "b" handshape
c. "l" handshape

Here are the answers to the given questions above.
1. The answer would be TRUE. It is true that to sign a comparative adjective in ASL, you would add the sign for the suffix -ER after the descriptive word is signed. 
2. Classifier in ASL is signs that are used to represent general categories or classes of things. These are designated hand shapes and/or rule-grounded body pantomime used to represent nouns and verbs. The answer would be option B.
3.  To indicate possession, hand shape should be "B" handshape. This is changing the handshape from an index finger to a flat hand (a version of a B palm); the palm should face toward the person or thing that's doing the possessing.
Hope these help.

Betray, destroy, and obey do not need to be changed to add the suffix -ed, because the "y" at the end of each word is preceded by a vowel  (so  they would be spelled  "betrayed," "destroyed," and "obeyed").

but hurry is different; it has to  be spelled "hurried" because the "y" at the end of "hurry" is preceded by a consonant.
