Use the QHT strategy to sort the following key elements of argumentation: purpose, audience, claim, evidence, reasoning, and counterclaim.

In Jun e 2007, Consumer Reports examined top-loading and front-loading washing machines, testing samples of several different brands of each type. One of the variables the article reported was "cycle time," the number of minutes it took each machine to wash a load of clothes. Among the machines rated good to excellent, the 98% confidence interval for the difference in mean cycle time $\left(\mu_{T o p}-\mu_{F r o n t}\right)$ is (-40, -22). Explain what that means about the two types of washers.

A solid is made by rotating the part of the curve with equation $y=(3 x-1)^{\frac{3}{2}} \text { from } x=\frac{1}{3}$ to $x=\frac{2}{3}$ through four right angles about the x-axis. Find the volume of the solid, giving your answer in terms of $\pi$.

Find the equation of the tangent to the curve $y=(4 x+3)^{5}$ at the point $\left(-\frac{1}{2}, 1\right)$, giving your answer in the form y = mx + c.

Select and record an interesting quotation-relating to the protagonist or setting-that you think is important to understanding the conflict or theme. Then, analyze the idea and form two thoughtful questions for discussion.

Emmeline Pankhurst explained in a 1913 speech why it was so important for women to have a voice in their government.

I wonder that a woman will face the ordeal of childbirth with the knowledge that after she has risked her life to bring a child into the world she has absolutely no parental rights over the future of that child." -quoted in Sources of the Western Tradition, Volume II: From the Renaissance to the Present. Based on the excerpt, with which argument would Pankhurst most likely agree? A. Women should not have to work in factories. B. Women have an obligation to take care of their families. C.
