WASHINGTON (Reuters) — The U.S. unemployment rate probably rose in October as employers stepped up hiring only slightly, underscoring President Barack Obama’s vulnerability in next week’s presidential election.

Employers likely added 125,000 jobs to their payrolls last month, according to a Reuters survey of economists. That would be up from 114,000 in September, but would 　 41　 short of what is needed to quickly cut the jobless rate.

Indeed, economists expect the unemployment rate — a key 　　42　 in the neck-and-neck race for the White House ——to tick up by a tenth of a percentage point to 7.9 percent, reversing part of a surprise drop seen in September.

The Labor Department's closely watched report, which will be 　 43 at 8:30 a.m. (12:30 GMT) on Friday, will be the last 　44 report card on the economy before Tuesday's presidential election, which pits (使竞争）President Obama against Republican Mitt Romney.

If economists are right, it will show the eighth straight month of dull job growth, a worrisome　 45 that would likely reinforce the Federal Reserve's resolve to keep easy money policies in place until the economy shows more vigor.

"The weakness in overall economic growth momentum has 　 46 into the last quarter of the year," said Millan Mulraine, an economist at TD Securities in New York.

Romney has made the nation's feeble jobs market, which has caused Obama a lot of trouble since he took office in 2009, the centerpiece of his 　 47 . The last Reuters/Ipsos daily tracking poll showed Obama and Romney in a 　 48　 heat.

Still, the report could provide fodder for both candidates. Some economists have 　 49　 an increase in the jobless rate might have a silver lining if it is driven by Americans pouring into the labor market to restart job hunts.

Like that of her own character, Harry Potter, J.K. Rowling’s life is like a fairy tale. Divorced, living on public assistance in a tiny Edinburgh flat with her infant daughter, Rowling 　1 Harry Potter and the Sorcerer’s Stone 　2 a table in a café during her daughter’s naps – and it was Harry Potter 　3 rescued her.

Many of her favorite 　7 center around reading – hearing The Wind in the Willows 　8 aloud by her father when she had the measles（麻疹）, enjoying the fantastic adventure stories of E. Nesbit, and her favorite story of all, The little White Horse.

At Exeter University Rowling took her degree in French and 　9 one year studying in Paris. After college she moved to London to 　10 as a researcher and bilingual secretary. The best thing about working in an office, she has said, was　 11 up stories on the computer when no one was 　12 . During this time, on a particularly long train ride from Manchester to London in the summer of 1990, the idea 　13 her of a boy who is a wizard and doesn’t know it. He 　14 a school for wizardry – she could see him very plainly in her mind. By the time the train 　15 into Kings Cross station four hours later, many of the characters and the early stages of the plot were fully 　16 in her head. The story took further shape as she continued working on it in 　17 and cafes over her lunch hours.

After her marriage to a Portuguese TV journalist ended in divorce, Rowling returned to Britain with her infant daughter and a suitcase full of Harry Potter notes and 　18 . She settled in Edinburgh to be near her sister and 　19 to finish the book before looking for a teaching job. Wheeling her daughter’s carriage around the city to escape their 　20 , cold apartment, she would duck into coffee shops to write when the baby fell asleep. In this way she finished the book and started sending it to publishers.
