History
Read this section of Dwayne’s text about physical science. Look around. Everything you see is made up of atoms, which are basic units of matter. Atoms that are linked together create a molecule, the most basic life form. A microscope is a tool used to look at very small objects. To see individual atoms, scientists must use a special microscope called a scanning tunneling microscope (STM). What should Dwayne do to help his readers understand the text, and why? A. Insert a diagram of a microscope with each part labeled so readers understand how scientists study atoms and molecules. B. Set the term “scanning tunneling microscope” in red font so readers understand that this is a key term that they should look up. C. Add a photograph of a scientist looking through a microscope with the caption “Scientists study atoms and molecules.” so readers will understand why scientists use microscopes. D. Insert the heading Atoms and Molecules above the first paragraph to indicate that paragraph’s main idea, and add the heading Microscopes above the second paragraph to indicate the main idea of that paragraph.

Ответ:
the fourth alternative is correct (d).
in contrast to the fact that the middle east has the largest oil reserves in the world, this region has the lowest amount of drinking water available for domestic consumption and industrial and agricultural activities.
this region has 5% of the world population, but only 1% of the water reserves in the planet, being the lowest rate of supply of water per person in the world. the current quota of water consumption by the inhabitants is approximately 1500m³ and the temptation is worsening in this scenario. according to data from the world bank in 2025, this rate should fall to 700m³.
seawater desalination technologies may be the outlet for the problem of nations in that region, but they are still very expensive.
