Answer: Thermal inversion
Explanation: Thermal inversion or change the position of the air layer, when the warmer layer of air is above the cold layer, which is usually not the case. It happens due to a change in the normal temperature gradient, i.e. when the gradient becomes inverted. Such thermal inversions can occur in oceanic areas with a lot of upwelling near the coasts. Thermal inversion also occurs when sun radiation is less than radiation from the earth, which is the case during the night. The significance of these inversions is great, especially for air quality in polluted environments such as urban. The strongest inversions are during the winter and can then be dangerous due to poor air quality, which is measured by the AQI (Air Quality Index). The higher the AQI index, the greater the risk of bad air, that is, the worse air.
Answer:
When the printing press was invented there was a shift from the laborious manuscript making to the codex print allowing many copies of written work to be quickly created, in turn providing greater access to information for all and providing the framework for the gradual transformation of societal literacy.The printing press had dramatic effects on European civilization. Its immediate effect was that it spread information quickly and accurately. This helped create a wider literate reading public.

C should be correct answer
The rabies virus spreads through animals (well known carriers of the disease are dogs and cats, there are also squirrels) and it can cause deadly affects. While the flu is passed around between humans and is easily treatable and a lot less deadly than rabies.
(Even though the flu can lead to death by causing a colossal amount of inflammation in a person's lungs, which can lead to respiratory failure. Also, when someone has the flu, they become more vulnerable to a bacterial infection that can lead to pneumonia.)
