Answer:
Size of the court
Explanation:
In the game of tennis, there could be a singles match typically involving just two players, or a doubles tennis which involves four players. The rule modified for the doubles tennis is that a wider court is used since there are more players involved.
Each player can serve the tennis after the fourth game. The server and receiver can stand at any side of the court even though it is ideal that they maintain one side.

The disease called as the Osteogenesis imperfecta is the genetic disorder which causes imperfect formation of bones.

Answer:
A. Vena cava
Explanation:
The aorta can't be the answer because it is the largest artery in the human body and it carries oxygenated blood. The pulmonary artery carries deoxygenated blood into the lungs for oxygenation. The pulmonary veins transfer oxygenated blood from the lungs to the heart. And lastly, the vena cava is the right answer and it returns deoxygenated blood back into the heart.
Depending on what your answer options are, it is either perspiration (sweat) or sweat glands.
