Question

below 40 °f. the crop needs around 15 inches of rain over the growing season; production will decline with less rain. a: greenland: average monthly precipitation chart with jan - dec, precipitation in inches b: greenland: average monthly temperature chart with jan - dec, temperature in °f, minimum (red) and average (blue) karr. scientific american: environmental science for a changing world, 4e, ©2021 w. h. freeman and company. based on the data provided, during what month could a farmer in greenland assume that barley’s growing season begins? ∘ june

Explanation:

Step1: Analyze temperature requirement

Barley needs temperature above \(40^\circ\text{F}\). Check average temperatures (blue bars) in each month.

Step2: Check monthly temperatures

• Jan: \(11^\circ\text{F}\) (too low)
• Feb: \(14^\circ\text{F}\) (too low)
• Mar: \(25^\circ\text{F}\) (too low)
• Apr: \(39^\circ\text{F}\) (too low)
• May: \(51^\circ\text{F}\) (above \(40^\circ\text{F}\))? Wait, no, wait the problem's initial text said "below \(40^\circ\text{F}\)"? Wait, no, the crop needs temperature? Wait, the original problem's first line: "below \(40^\circ\text{F}\). The crop needs around 15 inches of rain..." Wait, maybe I misread. Wait, the question is about when the growing season begins, considering temperature (needs above? Or below? Wait, the first line: "below \(40^\circ\text{F}\)" – maybe the crop grows when temperature is above? Wait, no, let's re - examine the temperature graph (B). Let's list average temperatures:

Jan: 11, Feb:14, Mar:25, Apr:39, May:51, June:60, etc.

Wait, the crop (barley) – the first sentence: "below \(40^\circ\text{F}\). The crop needs around 15 inches of rain over the growing season; production will decline with less rain." Wait, maybe the temperature needs to be above \(40^\circ\text{F}\)? Wait, no, the first part says "below \(40^\circ\text{F}\)" – maybe that's a condition. Wait, the question is when the growing season begins. Let's check temperature:

In May, average temperature is \(51^\circ\text{F}\) (above 40), but wait, the option given is June? Wait, no, maybe I made a mistake. Wait, let's check the temperature graph again. Wait, the minimum and average temperatures:

In June, average temperature is 60, minimum is 45 (wait, no, the red bars are minimum? Wait, the legend: red is minimum, blue is average. So in June: minimum is 45, average is 60. In May: minimum is 39, average is 51. Wait, the crop needs temperature above \(40^\circ\text{F}\)? So when does the minimum temperature go above \(40^\circ\text{F}\)?

June: minimum is 45 (above 40), May: minimum is 39 (below 40). So the growing season begins when temperature (minimum) is above \(40^\circ\text{F}\), so June? Wait, but let's check the precipitation too. The crop needs 15 inches over growing season. Let's check precipitation (graph A). From June to, say, later months. But the key is temperature. So when the minimum temperature is above \(40^\circ\text{F}\), which is June (minimum 45). So the answer is June.

Answer:

June
