Teeth: preposições dependentes (B2)

Dentistry is one of the few areas of medicine where prevention is cheap, effective and still unevenly applied. Water fluoridation at recommended levels reduces decay across an entire population without requiring anybody to change their behaviour, which is precisely why it works: no appointment, no cost, no need to remember. Its safety at those levels is no longer subject ___ serious scientific dispute, yet the policy is repeatedly abandoned in cities where campaigners frame it as medication without consent. Dentists respond that untreated decay is not a cosmetic matter. It causes infection, sleep loss and days missed from school or work, and it falls hardest on families who cannot afford private treatment. Where fluoridation stops, hospital admissions of children needing extractions under general anaesthetic tend to rise within a few years.

Ver gabarito comentado

Resposta correta: D

O adjetivo "subject" exige obrigatoriamente a preposição "to" quando significa sujeito a algo: subject to change, subject to approval, subject to dispute. Assim como depend on e result in, trata-se de uma preposição dependente, imposta pela palavra que a antecede. "Subject of" só ocorre quando subject é substantivo com o sentido de assunto, como em the subject of the debate, e não cabe nesta construção adjetiva. "Subject for", "subject with" e "subject at" não formam combinações reconhecidas em inglês padrão.
