Answer:
Tienen tantas camisas como nosotros.
Step-by-step explanation:
In this exercise, you have to select the best translation for the sentence given. The other sentence (''tienen tan camisas como nosotros'') is not correct because it does not make sense, it has no coherence and cohesion. If you remove the ‘’tan’’ it is okay because it means ‘’They have shirts as we do’’ but you would be leaving out the ''as many as’’.
