Read the sentences below and answer the questions.

Answer

  1. the first one (If you cross out the relative clause, the remaining sentence is Those missed the party. which doesn't make sense.)
  2. the second one (If you cross out the relative clause, the remaining sentence is Pedro missed the party. which still makes sense.)
