Analysing Scientific Interrelationships - Example 3

The first step in solving this item is to determine which curve shows the temperature and which curve shows the amount of precipitation. Since only the thickly drawn curve also exhibits negative values (see region R3), it must be the temperature curve.

In statement I, the annual precipitation amounts in the regions R1 and R4 are compared with one another. In region R1 the precipitation is greater than in region R4 in May, June and July. If we look at the year as a whole, however, the precipitation in region R4 is clearly greater than in region R1. Statement I is therefore wrong.

Statement II can be checked by looking at the temperature curve. In region R1, the temperatures are the lowest in June and July and the highest in December and January. Region R1 must therefore be located south of the equator. Statement II is therefore correct.

Therefore (B) is correct.
