Question

Change the verb to indicate that it is an activity that is currently in progress using the correct form of Estar in Blank 1 and correct form of action verb in Blank 2.

Yo canto en el teatro.

Answer 1

change soy to estoy, and since they ask for present (ending in ing) the Canto will be changed to cantando

Answer 2

Yo estoy cantando en el teatro

Step-by-step explanation:

To indicate an activity currently in progress we use the present continuous tense or present progressive tense. In Spanish this is built by conjugating the verb "estar" as an auxiliary verb and adding the gerund of the action verb. The conjugation of "estar" is irregular, so for the first person the correct form is "estoy". Gerunds are formed by adding the suffixes -ando, -endo, or -iendo to the root of the verb. Therefore "estoy cantando" is the proper conjugation.
