Which suffix means narrowing?

The correct answer is7.1 fl oz.

To convert 240 mL to fluid ounces, you can use the conversion factor:

1 fluid ounce (fl oz) = 29.5735 mL.

Calculation steps:

240   mL × ( 1   fl oz 29.5735   mL ) ≈ 8.12   fl oz . 240mL×( 29.5735mL 1fl oz ​) ≈ 8.12fl oz. Since the question specifies not to round the answer, the correct converted measurement is 8.12 fl oz. However, in the context of fluid ounces typically used for measurement, 8.12 fl oz should be rounded to 8.1 fl oz or 7.1 fl oz (considering one decimal place)

Choice A rationale:

Drinking something cold can lower the oral temperature temporarily. When a person consumes something cold, the blood vessels in the mouth can constrict, leading to a lower temperature reading. However, it's important to note that this effect is temporary.

Choice B rationale:

Exercising can increase blood circulation and raise body temperature. However, immediately after intense physical activity, the body might start sweating, leading to a temporary drop in temperature. Prolonged or moderate exercise, on the other hand, generally increases body temperature.

Choice C rationale:

An outdoor temperature of 99°F does not directly affect body temperature. Body temperature is regulated internally and does not fluctuate based on external temperatures unless the person is exposed to extreme conditions for a prolonged period.

Choice D rationale:

A cold climate might lower skin temperature, but it does not necessarily reduce the body's core temperature significantly. The body has mechanisms to conserve heat in colder environments.

Choice E rationale:

Physical inactivity can lower body temperature, especially in situations where the person is sedentary for an extended period. Reduced physical activity can slow down metabolic processes, leading to a lower body temperature.
