### HideShow timer Statistics

Temperatures in the Pacific Northwest have risen steadily since 1981, averaging 2.07 degrees Fahrenheit warmer north of the 46th parallel than in the previous decade. Preceipitation and water-table levels, which have historically maintained a measurable relationship to each other (within a scaled range of two to four points), have varied drastically from 1987 to 1991, sometimes deviating as mush as six points in fewer than eight months. Report from Canada indicate similar median temperature increase, estimated at 2.02 degree Fahrenheit;research from a 1992 study measures the relational swing in moisture levels at no more than three points.

of the following, which conclusion is best supported by the evidence above?
(A)The higher the temperature of a given area, the more likely it is that the water levels will vary
(B)The variation in temperature in the last decade has been less than the fluctuation of moisture
(C)When temperatures rise north of the 46th parallel, natural water exchange between land and atmosphere must change in the same proportion
(D)Within the last ten years, water table and precipitation levels have varied more in the Pacific Northwest than they have in Canada.
(E)Canada will have more stability in weather than with the area of the United States above the 46th parallel

I opt for E as the weather stability in canada will be better since the variation is only 3 points against 6 points

Are "Preceipitation and water-table levels" and "moisture levels" the same ?

(E)Canada will have more stability in weather than with the area of the United States above the 46th parallel

The only reasonable conclusion that can be made from the argument is that the water table and precipitation levels have varied more iin Pac.NW than in Canada.

E - How do we define weather? Is it defined by moisture, temperature, something else...

For this reason, E cannot be the correct answer.

If I had to choose 1, I will pick D.

D because all data provided in the conclusion fits with the info in the stimulus
