Answer:
B) These bags are heavy
C) I am not tired
E) My sister and I are good tennis players.
Explanation:
O verbo "are" é utilizado sempre que você utilizar os pronomes "you", "they" e "we", ou uma palavra equivalente a esses pronomes, como é o caso das frases " These bags are heavy
" onde "these bags" substitui o pronome "the" e na frase "My sister and I are good tennis players", onde as palavras "My sister and I" subatituem o pronome "we".
O ver "am", por outro lado, é utilizado sempre que você utilizar o pronome "I", como foi usado na frase "I am not tired
".
