To create the correct form, do this:

 

1. Start by deriving the stem by removing the -AR ending. 

• We take the "ar" off of "tomar"
   
• Our stem is "tom".

2. Look to the left of the blank to find the subject of the verb. 

• We see "ustedes", a 3rd-person-plural subject pronoun.
   
• We add the 3rd-person-plural ending, which is "AN" to the stem (tom).
   
• This gives us "toman", the correct conjugation.
