The position where the moon is located where its shadow may sometimes reach Earth is position A .
We know that in the outer space there are a lot of celestial bodies that can be found. Now we know that a celestial body is one that can be found in the outer space and the moon and the sun are all parts of the celestial bodies that we can find in the solar system.
In this case we are being asked for the position of the moon that could lead to an eclipse where the moon would come between the earth and the sun and that is the position A.

The position of the Moon’s shadow reaching Earth is not dependent on Earth’s position in its orbit around the Sun but on the relative positions of the Moon, Earth, and Sun. If the Moon is located directly between the Earth and the Sun, the Moon's shadow can sometimes reach Earth.
The position of Earth with respect to the Moon is not necessarily related to its position in its orbit around the Sun, but with the positioning and phases of the Moon relative to the Sun and Earth. When the Moon is positioned between the Earth and the Sun, we typically have a New Moon phase. During this positioning, if everything aligns perfectly, it is possible for the Moon's shadow to reach Earth, causing an eclipse. This can occur at any position of Earth's orbit around the Sun, provided the Moon is located appropriately.

B- greater thermal conductivity
C- greater thermal insulation
D- a higher R-value
Answer: The correct answer is "greater thermal conductivity".
Explanation:
Thermal conductivity: It is a ability to conduct heat. Heat transfers occur at a lower rate to material at higher thermal conductivity.
It is defined as the rate at which the heat is transferred through a unit thickness of the substance per area per change in the temperature.
In the given problem, A piece of wood and a piece of steel are at the same temperature. However, the steel feels hotter. The thermal conductivity of the steel is more than the thermal conductivity of the wood.
Therefore, the correct option is "greater thermal conductivity".
B- Greater thermal conductivity

Contaminated groundwater
Carbon monoxide
Carbon monoxide is an air pollutant that can contribute to asthma. Therefore, option D is correct.
Carbon monoxide (CO) is a colorless and odorless gas produced by the incomplete combustion of fossilfuels, such as gasoline, coal, and wood. It is primarily emitted by vehicles, industrial processes, and the burning of biomass.
When inhaled, carbon monoxide reduces the blood's ability to carry oxygen, leading to oxygen deprivation in the body. Prolonged exposure to carbon monoxide can worsen asthma symptoms and potentially trigger asthma attacks.
