Passage II

Precipitation events and drought affect a stream's discharge (rate of flow) at a given time. The discharges of 3 streams (Streams 1-3) in the same drainage basin were recorded continuously over a 10-year period ending in 2002. Figures 1, 2, and 3 show the daily average discharge of Streams 1, 2, and 3, respectively, for a 3-month period of drought during 2002. In addition, Figure 1 shows the maximum and minimum daily discharges of Stream 1 during the 3-month period in 2002. Each figure also shows the historical daily average discharge of the respective stream, obtained by averaging the daily average discharge for the same 3-month period over the 10 years. Table 1 shows the area drained by each stream.

10. Based on Table 1, the total area of the drainage basin mentioned in the passage is:

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

First of all, the article does not indicate the relationship between the three streams.

In the first case, it doesn’t matter how far apart the three rivers are, then the total area of ​​the drainage basin should be 314+31.9+75.4;

In the second case, there is Maybe the three rivers are directly related to each other as tributaries and main streams, so the drainage basins will overlap with each other, and the drainage basins of the tributaries are only part of the main stream drainage basin
