Questão

An after-school math club gathers every Tuesday to tackle challenging problems. Last week, the coach assigned a logic puzzle that involved arranging colored tiles in a grid. The students worked in pairs for over an hour. They solved the puzzle. The puzzle required careful analysis of each pattern. Afterwards, the coach congratulated the group and highlighted their teamwork. Some members shared strategies whose effectiveness surprised the coach. The meeting ended with plans for a geometry project that focuses on symmetrical designs. Analise the sentences 'They solved the puzzle.' and 'The puzzle required careful analysis of each pattern.' and identify the option that correctly combines them into a single sentence using a relative pronoun.

1. A) They solved puzzle whose required careful analysis of each pattern.
2. B) They solved the puzzle which required careful analysis of each pattern.
3. C) They solved the puzzle who required careful analysis of each pattern.
4. D) They solved the puzzle which require careful analysis of each pattern.
5. E) They solved the puzzle that required careful analysis, of each pattern.

✅ Resposta correta: alternativa B

Resolução passo a passo

1. Identifique as duas orações. A primeira, 'They solved the puzzle.', é completa. A segunda, 'The puzzle required careful analysis of each pattern.', fala sobre o mesmo quebra-cabeça, que é a ideia repetida que o pronome relativo deve substituir. Passo 2: Como o antecedente é a coisa 'the puzzle', o pronome relativo adequado é 'which' (ou 'that'), e a oração relativa deve vir logo após 'the puzzle'. Passo 3: Monte a frase combinada: 'They solved the puzzle which required careful analysis of each pattern.' A oração relativa restritiva 'which required careful analysis of each pattern' mantém o verbo no passado, concordando com a primeira oração, e a estrutura 'careful analysis of each pattern' fica íntegra. Passo 4: Por que as outras estão erradas. A: 'whose' precisa ser seguido de um substantivo (por exemplo, 'whose analysis'), e a frase também omite o artigo 'the' antes de 'puzzle'. C: 'who' é pronome relativo para pessoas, e aqui o antecedente é um quebra-cabeça. D: 'require' está no presente, enquanto a frase precisa do passado 'required', e não concorda com o sujeito singular 'which'. E: 'that' poderia funcionar, mas a vírgula inserida entre 'analysis' e 'of each pattern' separa indevidamente o complemento do substantivo, quebrando a expressão. Conclusão: a alternativa correta é a B, que coincide com o gabarito oficial.

💡 Dica: Preste atenção ao uso correto do pronome relativo e à concordância verbal.
