According to the text, it is CORRECT to affirm:
Missing Dentures Found Stuck in Man's Throat 8 Days
After Surgery
Here’s why it’s best to remove false teeth before
surgery: You just might swallow them.
A medical journal is reporting the case of a 72-
year-old British man whose partial dentures apparently
got stuck in his throat during surgery and weren’t
discovered for eight days.
The man went to the emergency room because he
was having a hard time swallowing and was coughing up
blood. Doctors ordered a chest X-ray, diagnosed him with
what they wrongly thought was pneumonia and sent him
home with antibiotics and steroids. It took another
hospital visit before another X-ray revealed the problem:
His dentures — a metal roof plate and three false teeth —
lodged at the top of his throat.
The man thought his dentures were lost while he
was in the hospital for minor surgery.
How it happened isn’t exactly clear, but a halfdozen previous cases have been documented of dentures
going astray as surgical patients were put to sleep. Placing a tube in a patient’s airway can push
things where they don’t belong, said Dr. Mary Dale
Peterson, an anesthesiologist at Driscoll Children’s
Hospital in Corpus Christi, Texas. Besides dentures, retainers, loose teeth and
tongue piercings can cause problems, said Peterson, who
is president-elect of the American Society of
Anesthesiologists. Before a child’s surgery, she’ll pull a
very loose tooth and tell the patient to expect a visit from
the tooth fairy. "We can make a nice game of it." In the British case, after the dentures were
removed, the man had several bouts of bleeding that
required more surgery before he recovered. The journal
article didn’t identify the man or the hospital involved. […]

Gabarito comentado
Alternativa correta: D
Tema central: interpretação de texto — identificar a ideia principal e inferências a partir de informações explícitas. Aqui é necessário distinguir o que o texto afirma diretamente (dentes falsos ficaram presos na garganta durante/apos cirurgia) do que não diz.
Resumo teórico rápido: em reading comprehension, foque em (1) sujeito e ação principal; (2) marcadores temporais; (3) expressões categóricas (ex.: “half-dozen previous cases” contradiz absolutos como “never”); (4) pronomes e concordância que podem mudar o sentido. Fonte de apoio: práticas de compreensão de textos jornalísticos (ex.: NBC News — matéria base).
Justificativa da alternativa D: o texto relata que um homem de 72 anos teve suas partial dentures “got stuck in his throat during surgery” e só foram descobertas oito dias depois. Isso corresponde exatamente a “an elderly man has ingested his dentures during surgery” — é a ideia central e literal do trecho. A citação do anestesiologista explicando como a intubação pode empurrar objetos reforça essa explicação. (Fonte: matéria do NBC News citada no enunciado.)
Análise das alternativas incorretas:
A - “doctors missed their false teeth after surgery.” Errada: além do pronome “their” tornar a sentença ambígua (sugere que os médicos perderam seus próprios dentes), o texto fala dos dentures do paciente, não de médicos. Não corresponde ao sentido original.
B - “the patient’s implants were removed before surgery.” Errada: o texto não diz que “implants” foram removidos antes; ao contrário, sugere que o paciente possivelmente não removeu as próteses antes da cirurgia. “Implants” é termo distinto de “partial dentures”.
C - “surgical patients have never lost dental plates in surgery.” Errada: o texto menciona que “a half-dozen previous cases have been documented”, logo a afirmação “never” é contraditada explicitamente. É uma alternativa absoluta e, portanto, falsa.
Dicas de prova: busque a correspondência literal entre enunciado e alternativas; desconfie de palavras absolutas (never, always) e de mudanças de sujeito/pronome; use marcadores temporais e citações diretas do texto para confirmar a resposta.
