Ead the excerpt from the dark game: true spy stories from invisible ink to cia moles.

wyke's work was always delicate and demanding, more so in the damp and confined space. gently and carefully, wyke scraped the dirt until he found the three cables encased in black rubber and, he believed, pressurized by nitrogen, a common practice in the 1950s to keep moisture out of cables. he knew that once he cut through the rubber sheathing on the cables, the nitrogen would escape. the resulting drop in pressure would be detected by the soviets. the engineers solved this potential problem by building a concrete barrier with a steel door to pressurize the tap chamber and separate it from the pre-amp room. (it turned out that the cables were not pressurized.)

wyke next attached wires to the exposed cable—probably with alligator clips—and began to draw power from the cables. once again, the work called for a deft hand. if he drew off too much power, the soviets would be sure to notice it. as expected, wyke did a masterful job, and the tapping began on may 11, 1955.

What do the sketches of 9/11 victims in "portraits of grief" achieve?

Read this excerpt from "herd about the flu." the flu shot prevent huge numbers of infections. even when it doesn't fully prevent infection in every person, the shot makes any flu infection less serious. on a global scale, the vaccine can reduce the number of infections only if most people in the community take it. that's because vaccines need to reach enough people to achieve a "herd immunity," the level of immunity needed to prevent the virus from spreading. if too few people get the vaccine, the people who receive it may not be well protected against infection. so the next time you are at the drugstore, and you see no flu shots available, think about the reasons behind it. drug makers are scared to make too many flu shots because they could lose too much money. they then make fewer flu shots and the effect of the flu shots becomes weaker because not enough people take it. people become more reluctant to take the flu shot since they don't think it will fully work. the demand goes down further and the flu companies make even fewer shots the next year. this could continue until the community changes its mind and we all get the flu shot. "that is a community responsibility," says the president of merck, one of the two remaining flu vaccine manufacturers. which argument best supports the passage's claim that more people should get the flu vaccine to stop the virus from spreading? 1.if too few people get the vaccine, the people who receive it may not be well protected against infection 2. so the next time you are at the drugstore, and you see no flu shots available, think about the reasons behind it. 3.people become more reluctant to take the flu shot since they don’t think it will fully work. 4.drug makers are scared to make too many flu shots because they could lose too much money.
