There are many things one can infer from these civilizations just by
knowing that they were able to build such massive structures. One was
that they had a running civilization which was able to provide for its
citizens in adeqaute amount - this allowed them to be able to undertake
such feats.
Another thing is that we know they had the necessary
knowledge to actually build such structures - this tells us that they
were relatively advanced for their age and time.
Another thing
we can know from this is that they probably valued some sort of rituals
and had people who were at a higher level in society who also commanded
for these structures to be built.
The answer to your question is 1962
Your answer is B.
hope this helps.
A negligible difference. Wind speed of 40 mph generally does not change the temperature of the air that much.
However, I believe you are meaning to ask what the difference feels like if you were subject to these conditions, this is a more complex answer. (Assuming that your skin temperature is greater than 35 degrees) You first need to understand that a change in wind speed would only decrease the time taken for your skin to equalise it's temperature to the surrounding air and thus feel 'colder', this is because more air is flowing over your skin per unit of time.
There are multiple other factors in determining what the 'feels like' temperature would be, such as taking into account the humidity and density of the air combined with our understanding of how heat is lost from the human body.
