Hi, you've asked an incomplete question. The remaining part of the question reads;
the first paragraph;
<em>I spent my teens and much of my twenties collecting printed rejections. Early on, my mother lost $61.20—a reading fee charged by a so-called agent to look at one of my unpublished stories. No one had told us that agents weren’t supposed to get any money upfront, weren’t supposed to be paid until they sold your work. Then they were to take ten percent of whatever the work earned. Ignorance is expensive. That $61.20 was more money back then than my mother paid for a month’s rent.</em>
The last sentence of the first paragraph (“That . . . month’s rent”) primarily serves to
A. <em>justify an action by invoking an ethical principle</em>
B. clarify a point by defining an ambiguous term
C. show how anecdotal evidence supports a claim
<em>D. provide meaningful context for a revealing statistic</em>
<em>E. demonstrate that a common practice has harmful effect</em>
Answer:
<u><em>D. provide a meaningful context for a revealing statistic</em></u>
Explanation:
By saying, "<em>That $61.20 was more money back then than my mother paid for a month’s rent" </em>the narrator had revealed a very interesting statistic about the value of money back then.
In other words, the context surrounding the statement helps the average reader quickly understand that a month's rent used to be <em>lesser</em> than $61.20; very interesting statistics at that.
The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years

Answer:
climate change would increase income inequalities between and within countries. a small increase in global mean temperature (up to 2 °C, measured against 1990 levels) would result in net negative market sector in many developing countries and net positive market sector impacts in many developed countries.
