Of the 263 transboundary basins, _____ are shared by two or more states.

Question

Quizplus · Accepted Answer

The question states that there are 263 transboundary basins, and asks how many are shared by two or more states. This means that we are excluding basins that are entirely within one country. The answer options refer to fractions of the total number of transboundary basins, so we need to convert each fraction to a number: 
- Two thirds of 263 is about 175
- One third of 263 is about 88
- Half of 263 is 131.5 (which is not a whole number)
- Three fourths of 263 is about 197.

Since we are looking for basins shared by two or more states, we are essentially asking for the number of transboundary basins that are not entirely within one state. The only option that represents a minority of the total number of transboundary basins is B) One third. Therefore, the correct answer is B) One third.
