Match the weather observation in column 1 to the most likely result in column 2. Please help me out on this

Explanation:

When centimetres of mercury fall, it indicates that air pressure is decreasing which subsequently leads to rainfall.

When centimetres of mercury rise, the barometric pressure increases too which often leads to sunny and clear skies.

Dew point less than 10°C and temperature falling to 12°C at night would create  two air masses with different densities creating a weather front.

Temperature and pressure fall in the late evening would result in no droplets formed on ground.
