Because there no choices there, most probably it should be about hydrogen bonding in the water, which is the most important intermolecular force in water.
it is called the partial pressure because it is pressure that is exerted by each gas in a mixture of gases if it occupy the same volume of it own. the the partial pressure of oxygen in the air sample above is 100 mm hg, that of carbon dioxide is 40 mmhg, for water vapor 47 mmhg. and that of nitrogen is 573 mmhg
