Final answer:
John would often experience extremely high temperatures living in an area with high sun's rays and low latitude, as more direct sunlight leads to greater ground heating.
Step-by-step explanation:
If John lived in a place where the sun's rays are very high but the latitude is low, the temperature would quite often be extremely high. This is because as the sun appears higher in the sky, as in the summer months, its rays hit the Earth more directly and spread out less, resulting in more effective heating of the ground.
The angle of the sun's rays is a significant factor in determining the temperature; the more directly the rays hit the Earth, the more heat is transferred to the ground. Hence, in low latitude areas where the sun is typically higher in the sky, the temperatures tend to be higher.
For instance, near the equator, the sun's rays hit the Earth at a near-perpendicular angle throughout the year, leading to consistently high temperatures. This contrasts with higher latitudes where the sun's angle varies significantly with the seasons, contributing to larger temperature variations.
Therefore answer is a. Extremely high.
