Passage VI
Earth's atmosphere consists of various gases and suspended liquid and solid matter. The atmosphere can be divided into layers based on air temperature and/or composition. Figure 1 shows the layers of the atmosphere, the altitude of the layer boundaries, in kilometers (km), and the air pressure, in millibars (mb), at those boundaries. Figure 2 shows the average air temperature, in degrees Celsius (°C), in arctic (cold) and tropical (warm) air masses at various altitudes. Table 1 shows air pressure and temperature readings from weather instruments carried into the stratosphere by balloons on 2 separate days.
33. According to Figure 1 and Table 1, if the weather instruments rose above 13.7 km, the air pressure would most likely:
Your Answer is
Correct Answer is C
Explanation
Looking at figure 1, it is found that the higher the altitude, the lower the air pressure. When the altitude is 13.7 km, the air pressure should drop below 301 mb, so option C is in line
