{'higher altitudes': [0, 0, 0, 1], 'normal lapse rate': [0, 0, 0, 3], 'ascent': [0, 0, 1, 1], 'temperature': [0, 1, 1, 7], 'many metres': [0, 1, 0, 1]}

Option 1: Every 100 meters

This option suggests that the temperature decreases by roughly 16 degrees Celsius for every 100 meters of ascent. However, this is not the correct answer.

Option 2: Every 165 meters

This option states that the temperature decreases by roughly 16 degrees Celsius for every 165 meters of ascent. According to the given information, this is the correct answer. It means that as we go higher in altitude, for every 165 meters we ascend, the temperature will decrease by approximately 16 degrees Celsius.

Option 3: Every 225 meters

This option suggests that the temperature decreases by roughly 16 degrees Celsius for every 225 meters of ascent. However, this is not the correct answer based on the given information.

Option 4: Every 285 meters

This option states that the temperature decreases by roughly 16 degrees Celsius for every 285 meters of ascent. However, this is not the correct answer based on the given information.

Therefore, the correct answer is option 2, which states that the normal lapse rate of roughly 16 degrees Celsius is observed for every 165 meters of ascent.
