[单项选择]More than a week after slamming into the East Coast, Hurricane Sandy is causing headaches in payroll. Companies largely excused worker absences immediately after the storm, which left millions without power and tens of thousands temporarily homeless. But as businesses around the region return to normal, managers are struggling with how much, and how long, to pay employees who cannot make it in to work.
PNC Financial Services Group closed several hundred bank branches when the storm hit Oct. 29, and by Monday had reopened all but 90 locations in New York, New Jersey and Pennsylvania. All salaried and hourly employees were paid as usual while their branches were closed, said spokesman Fred Solomon, adding that more than 10,000 workers living in storm-ravaged areas on the Eastern Seaboard were given an additional five paid days off to use as needed.

Which of the following, if true, most seriously weakens the argument above
A. A small amount of the magnesium salts from the first plot leached into the second plot.
B. Tomato plants in a third experimental plot, to which a high-nitrogen fertilizer was added, but no magnesium salts, produced 15 pounds of tomatoes.

Will chips one day be planted in our bodies for identification
A US doctor has planted under his skin a computer chip that can send personal information to a scanner(扫描仪), a technology that may someday be widely used as a way to identify people. The chip gives off information which will be scanned by a hand-held reader.
The chip is similar to those planted in more than one million dogs, eats and other pets in recent years to track and identify them.
The doctor decided to test the chip himself after the Word Trade Center disaster. The dead could have been identified if their names and other important information had been chipped.
Officials of the company said they hope to sell the chips to patients with man-made arms or legs or other body parts. The idea is that the chip will provide immediate and correct medical information when it is needed.
The information can contain name, telephone number and other information. Or it can send out a mess
A. catch escaped prisoners
