Les agrees to install a new hard drive and modem on marilee's computer in exchange for four of her used textbooks. after he installs the hard drive, les says he won't install the modem unless marilee gives him two more books. what legal position are the parties in now?

Answer and Explanation:

Here, in this particular case it is given that Les had agreed to install a modem and hard disk on Marilee's personal computer in return for the four of her textbooks, but apparently Les only installs the modem and further refuses to install the hard disk unless and until Marliee provides  her with two more text books. Therefore in this case, Marliee can further tend to sue Les for the breach of the agreement, since in this case Les already had the duty to install both modem and hard disk.  

even though you have attached neither the chart nor the generalizations, i have located them online. the right answer is d, since they are asking you about a generalization. you can only infer from the chart that between 2008 and 2009 the number of employed workers decreased significantly (from over 115 millions to 107 millions approximately), which signals some type of economic crisis.
