Question

question 2
this prefix modifies a root word adding the meaning:
other, different; different member of the same species
xeno-
neo-
homo-
allo-

Explanation:

• neo -: It means "new", not relevant to the given meaning.
• homo -: It means "same", which is the opposite of what we need.

Answer:

allo-
