Hello,
Well, The word's that I translated was exercise,work,clean,and dance.
They need to look like exercis(ed),clean(ed),Work(ed),and danc(ed). These are verbs because a verb is a action. These are action's. So the reason why I put a (ed) on each word was because these are past tense.
So this is it translated.
<span>El lunes estudio historia. El martes ejercité. El miércoles trabajé. El jueves lo limpié. El viernes bailé
Hope this helps</span>
Answer- Conocen
Because if you say “Saben” it doesn’t fit correctly in the way the sentence is stated
do you understand the hand writing?
