Answer:

The right answer is B.

*Hydrogen is the most abundant element representing nearly three quarters of the mass of the universe.

*Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter.

*Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).

*Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table.

*Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.

Alex17521 [72]

Answer:

The paragraph shape I would use to narrate a football game would be an inverted triangle paragraph.

Explanation:

The reasons behind this answer are: First, the inverted paragraph triangle is a format of the text that allows the writer to expose the information in a hierarchical order. Therefore, the writer starts with the most relevant information to present a wide view of the event. Then, the writer presents information that is crucial to the topic but that is supplementary to the first general information. And finally, the writer provides supplementary information to highlight details from the event that have already been described. In a game, general information is the teams, the winner and loser, and the score table. Then, the event that leads to the winner win, and finally supplementary information about events related to the match.
