Hello,
The answer is option D "<span>a diary entry from an American homemaker in 1933".
Reason:
The answer is option D because the diary of a homemaker from 1933 is the original source of a subject that people can write off of and learn about. A primary source is the original source of a subject for example of homemaking. Its not option A because a magazine summary of the history of voting is not the original version of the history of voting. Its also not option B because a blog entry about how Roosevelt is the most important president is just a opinion. Its also not option C because a book about the civil war that was written by a historian wouldn't be the original source since how he or she gets the information from other sources in order to write the book.
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
new moon sorry if its wrong-
Explanation:
Cold and it is harder to breathe
Concept of effect:
The venturi vessel is simply implemented in the various procedures to obtain the increased value of velocity,v by constriction of the vessel's diameter or the total area required for the flow of liquids inside the vessel.And the decrease due to the constriction of the vessels area required for the flow of liquids.
But, we are provided we the given data in order to find the resultant value for the pressure,P inside the vessel.
<u>Given data:</u>
V=90 m/sec(the velocity,v at the inlet),
At=0.005,
V=90 m/sec,
∫∞=1.23 kg/m³,
V₁=√(P₁-P₂)/∫infinity[(area,A₁/final year,A)⁻¹],
Pressure,ΔP=1913.31 N/m².
