Studies have found that human body's intolerance to cold varies significantly over a
lifetime. Senior citizens, especially men aged 60 and above, are reported to be relatively
less able to maintain their body temperature at a given cold exposure than young people
do. The cold-triggered rise in metabolism is weakened in older people. Apart from that,
older adults are slower to react to the cold and, thus, generate less body heat in defense.
Normally, our skin reacts to cold by contracting surface blood vessels in protection, which
is also slower with age. It is noted in The International Journal of Sports Medicine that
older people have reduced skin sensitivity and a subjective perception as to how cold it is.
Some can develop hypothermia even after exposure to mild cold weather or a small drop in
temperature. Thereby they are more vulnerable to death from hypothermia.
At any age, cold sensitivity is related to one's health condition in general. For
example, the body's response to cold can be diminished under the influence of factors such
as thyroid malfunction, diabetes and an abnormally low body mass index, as well as some
medicines, including over-the-counter cold remedies. The best way to identify someone
car
with hypothermia is to look for confusion or sluggishness, weak pulse, slurred speech,
shivering or stiffness in the arms and legs. If you suspect that someone is suffering from
the hypothermia and you have a thermometer available, take his or her temperature. If it's
lower than 95 degrees Fahrenheit, call 911 for emergency medical treatment.

A
42. What can we infer from the passage?
(A) The normal body temperature should be much higher than 95 °F.
(B) Hypothermia can be best avoided if a thermometer is ready at hand.
(C) Older people need more exercise in order to achieve a longer life span.
(D) Aged people who are exceptionally thin are more likely to find cold weather
intolerable.

此題答案在第二段第一句最後開始：舉例而言，人體對低溫的反應程度會受一下幾個因子影響而下降，像是甲狀腺功能低下、糖尿病和「異常低的身體質量」...。此處「異常低的身體質量」就是低體重，即選項D中的thin。

選擇A較不好的原因是，雖然在文章最後一句說明：如果體溫低於華氏95度時，需要呼叫救護車並實施緊急醫療處置。但文章並無說明，正常體溫應要比華氏95度高出很多（much higher than 95°F），因此選D較為合適。
