Question

what can be concluded from the image?
a. most of the freshwater on earth is found in oceans.
b. most of the water available on earth is not drinkable.
c. most of the water available on earth is drinkable.
d. most of the freshwater on earth is found as groundwater.
other saline water 0.9%
total global water
oceans 96.5%
freshwater
glaciers & ice caps 68.7%
groundwater 30.1%
surface/other freshwater 1.2%

Explanation:

• Option A: Oceans have 96.5% of total global water, but oceans are saltwater, not freshwater. So A is wrong.
• Option B: Total global water has 96.5% ocean (saltwater) and 0.9% other saline, 2.6% freshwater. Most water is saline (non - drinkable), so most available water (including saline) is not drinkable. This makes sense.
• Option C: Most freshwater is in glaciers/ice caps (68.7%), not easily drinkable. And most total water is saline. So "most water available is drinkable" is wrong.
• Option D: Freshwater has 68.7% in glaciers/ice caps, 30.1% groundwater, 1.2% surface. So most freshwater is in glaciers, not groundwater. D is wrong.

Answer:

B. Most of the water available on Earth is not drinkable.
