You didn’t put any of the choices for the risks, but I believe something important to consider is making sure that the tourists return the umbrellas.
In the periodic table, the atomic radius of the atoms decrease from left to right. This means that Carbon is smaller than Boron. So from the choices you can rule out the first and third choice.
Now, the reason why Carbon is smaller than Boron is because Boron has more protons and as the protons increase it attracts the electrons closer, which makes the atom smaller.
Carbon has more protons, so it exerts a greater pull. The answer is then Option 2: Boron has a larger radius and the protons in carbon exert a greater pull.
As for the second question, a compound is defined as a substance that is made up of two DIFFERENT elements that are chemically bonded. If you look at the second option, it is a compound. It is made up of hydrogen and oxygen atoms.
The answer is then option 2.

Baryonic dark matter may occur in non-luminous gas or in Massive Astrophysical Compact Halo Objects, and stars. So therefore it’s D.
