Final answer:
Tennis clothing should be lightweight and cool to help maintain comfort and performance during play. Unlike tight-fitting body suits used in swimming, tennis clothing should allow for free movement and balance between temperature control and mobility. The correct option is A.
Step-by-step explanation:
The correct answer to the student's question, 'Tennis clothing should be _________.' is lightweight and cool. This choice helps players maintain comfort and peak performance by regulating body temperature and allowing freedom of movement. On the contrary, wearing warm pants and a raincoat can be cumbersome and too hot for players, negatively affecting their ability to play.
In comparison, loose-fitting white clothing worn by desert dwellers is also designed for comfort in extreme conditions. During the day, the light color reflects the sun's rays, helping to keep the individual cool, while the loose fit allows air to circulate, aiding in the evaporation of sweat. At night, the same clothing helps to retain some heat as temperatures drop.
While tight-fitting body suits like those worn in swimming may help reduce drag and enhance performance, in sports like tennis where movement is more varied and matches last longer, such constraints can lead to cramping and overheating. Thus, outfits in tennis are designed to balance comfort, temperature control, and mobility. Synthetic materials may or may not be favored, depending on their breathability and moisture-wicking properties.
