So first we need to identify what number 1,2,3, And 4 mean.We also need to identify what the sentence is saying."los salvadoreños estan _____ Las vacaciones de noviembre" Means "The salvadorans are_____ There vacations of november" Now that we have identified the sentence and the answers we can proceed. Bailando means dancing but if we filled in the blank with dancing the sentence wouldn't make sense. Leyendo means reading that wouldn't make sense either because they would be reading there vacations.Estudiando means Studying SO that wouldn't make sense either. Lastly. Disfrutando means enjoying so the answer is 4 or disfrutando
Hope this has helped :)
