I’m guessing a volcano. Hopefully this is right.
It has opened new trade routes and we can see what they used for their roads and we can make ours better.
The psychrometer is a device used to measure the
Relative Humidity (RH) of the air.
Relative humidity is the ratio of
(the amount of moisture in the air, here and now)
to
(the amount of moisture the air could hold at this temperature) .
Being a ratio, it has no units. It's just a naked number, always
less than ' 1 ', and usually expressed as a percent.
The additional information that will guarantee that the quadrilateral QUAD is a rhombus would be that all the sides have equal length, and that the opposite angles are the same.
The rhombus is a simple quadrilateral in which all of the four sides have the exact same length. In this case, since the sides UA and DA are 4 inches each, the sides QU and QD will also have the same length.
Also, the opposite sides are parallel, so we will have two sets of parallel sides with the same length.
The opposite angles in the rhombus are the same, so we would have two sets of opposite angles with the same values.
