Answer:
The answer to the first one is a. Harvey described the way the human body works in a way that made it seem less mysterious.
The answer to the second one is b. Newton was the first to show that nature is ruled by a set of laws that allow us to predict outcomes.
Explanation:
William Harvey was the 1st one to accurately find and explain the system of blood circulation inside the human body.
Prior to his findings, how the human body functions was a total mystery and many people believed in religious superstitions and miracles.
Sir Isaac Newton discovered the the idea of gravity, rules of motion, calculus and any more. He is regarded as one of the greatest physicists of all human history.
But his 3 laws of motion allowed to realize a lot of people that the nature works according to a set of natural laws and not because of the will of some deity or a god.

The Aswan High Dam was built to regulate and control the annual flooding of the Nile River in order to protect crops and property from such uncontrolled flooding and to generate electricity. Most of its effects have been positive but several environmental effects are:
- Water-logging: because of the continuous high levels of water, the soil around the area is saturated with water, which prevents oxygenation of the soil that is essential to several plants and crops.
- Salinization of soils: caused by the inability of water-saturated soils to absorb salt, it is toxic to crops and damaging to infrastructures.
- Soil Erosion: it is a consequence of soil salinization as crops die and are unable to hold the soil in place.
There were also other negative effects such as:
- Archeology: two important archeological sites of Ancient Egypt were flooded and covered by the dam waters: the ancient cemetery of Fadrus and the Buhen fort.
- Loss of sediment: the annual flooding carried an enormous amount of sediment that is now trapped within the resulting Lake Nasser. Many of these sediments were used by local industries to manufacture bricks and they lost access to this renewable source of raw materials.
- More expensive and difficult purification of water: because the water does not move as much it is more transparent and allows the sunlight to penetrate deeper. This, combined with the trapped sediments has increased the growth of algae that have proliferated to the point that water purification is more and more expensive due to the necessary removal of this plant.
