I think this belongs more in World Languages section but I know Spanish so this should be a piece of cake. Now the preterit tense is<span> (</span>el pretérito) in Spanish-it is the past tense examples are: -ar -er and -ir always keep these in mind. The correct<span> preterite ending is depending on who the subject of the action is. </span>These are the options presented in your question:
Bebimos= past tense (we drank) imos is the verb.
Bebemos= present tense (we drink)
Bebi= past tense (I drank) i in bebi is the verb.
Bebemos is the present tense so it can't be. Understand "el pretérito" now?
