Answer and Explanation :-

Answer: Option 4


The Moon is similar to the Earth in that it has a crust, mantle, and core. Scientists have samples of the lunar crust and take measurements of properties of the Moon's surface. The crust consists of 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, and trace amounts of other elements including 0.42% chromium, 0.18% titanium, 0.12% manganese, and smaller amounts of uranium, thorium, potassium, hydrogen and other elements. These elements form a concrete-like coating called regolith. Two types of Moon rocks have been collected from the regolith: mafic plutonic and maria basalt. Both are types of igneous rocks, which formed from cooling lava.

We must be content to grow slowly. Most of us will still barely be at the beginning of our recovery by the time we die. But that is better than killing ourselves pretending to be healthy.
