In the winter, cold, dry air masses tend to dominate the central and eastern United States as cold winds blow from the northwestern Canadian prairies. In summer, the warm southern winds blow moist, hot air into the eastern and central US, leading to days of high humidity and sultry conditions. In spring and fall, moving low and high pressure areas pull alternating warm and cold air masses across a given area, leading to a lot of variability in day-to-day weather.
People refer to "Darwin's finches" from time to time as a symbol of evolution in the Galapagos Islands, but the father of evolutionary theory actually dropped the ball on those birds, collecting better details on mockingbirds, tortoises and other species.
Charles Darwin's observations, notes and collected organisms from the Galapagos Islands during his 5-year voyage on the Beagle resulted in his theory of evolution by natural selection, one of the best substantiated theories in the history of science.
He collected several finch species, including the warbler finch, sharp-beaked finch, ground finch, small tree finch, large tree finch, common cactus finch and large ground finch.

Answer:
<em>The correct option is increased death rate</em>
Explanation:
Germ theory can be described as a scientific theory which depicts that microorganisms are the cause for many diseases which occur in humans, animals and plants. These microorganisms are known as pathogens or germs.
The formation of the germ theory led scientists to understand the pathogens involved in causing many diseases and hence scientists brought forward methods to kill the pathogens causing these diseases. Hence, the death rate did not increase after the germ theory.
