hire
The sentence means they need people and are willing to pay high wages in order to keep them from leaving. The correct verb is "retain". "Hire" would mean employ, but the phrase "pay high wages to hire them" is less natural here and does not fit the idea of keeping existing people. "Entertain" and "enrich" do not fit the context.

The other options are incorrect because the President does not administer the oath to the Governor, and the Chief Justice of India or the Speaker of the Legislative Assembly have no such constitutional role.

Choose the odd one out in terms of dimensional unit
A)
Specific gravity
B)
Strain
C)
Stress
D)
None of these
Specific gravity and strain are both dimensionless quantities. Specific gravity is a ratio of densities, and strain is a ratio of change in length to original length, so neither has a dimensional unit. Stress, however, is force per unit area, so its dimension is M L^-1 T^-2. Therefore, stress is the odd one out.
Lime is sometimes applied to soil in order to
A)
increase the alkalinity of the soil
B)
increase the acidity of the soil
C)
restore nitrates to the soil

make the soil more porous
Lime (usually calcium oxide, calcium hydroxide, or calcium carbonate) is applied to acidic soil to neutralize excess acidity and raise the soil pH. So its main effect is to increase the alkalinity of the soil. It does not increase acidity, and restoring nitrates or making soil more porous are not its primary purposes.

The other options are incorrect because heavy water is not used as a lubricant, sealant, stabiliser, or dilutant in reactors.
