American researchers found females are the more talkative sex because of a special "language protein " in the brain. The study, conducted by neuroscientists and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day - over 13,000 more than men. "This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals," said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends. They separated four-day-old rats from their mothers and then counted the number of times they cried out in the "ultrasonic range", the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother's cage, she _ her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less "talkative". The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans. "Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,"... Which of the following can be the best title for the passage ? A) Tests on humans and rats B) Why women are the talkative sex C) Sex differences in Foxp2 protein D) Foxp2 protein determines oral ability

*Question*
An increasing number of people are being allowed to finish the working week early during the summer months. Does your boss trust you to spend an afternoon in the sun? Each year the number of companies which offer employees the choice of an early finish to the working week grows. Or, perhaps, each year,more people who work on ordinary Fridays hear about people playing on summer Fridays. When the sun is shining,it makes sense that you should be given Friday afternoons off,right? Sadly,not all managers agree with the policy. Companies that offer employees Friday afternoons off usually expect the hours to be made up. UK publishers Pan Macmillan and Penguin Random House (PRH) are among those offering summer hours. At PRH, those who wish to take off Friday afternoons are expected to work an extra 45 minutes a day from Monday to Thursday. On Fridays, a rota ensures each team has been covered. "Most of us don't leave at exactly lpm,"Editor Anderson says. Depending on your workload,you might just leave an hour or so early,but it's still nice to do. " Simon Hayward, CEO of Cirrus, says that the "Summer Fridays" policy requires trust, and that managers need to be seen to take advantage of the offer too. "If a manager offers summer Fridays and then obviously expects employees to work on Friday afternoons, there is a risk associated with it that reduces the sense of well-being .I think there's a genuine fear in some organizations about flexible working hours. Do you trust your employees to do their best for the buti- ness as well as for themselves and their families,or do you fundamentally mistrust them?" Managers in the former camp tend to be comfortable with summer hours. Those in the latter worry that summer Fridays will lead to late Mondays and long-lunch Tuesdays. What's the good policy for some employees in summer? A) They don't work on Friday. B) They have flexible working hours on Friday. C) They can take Friday afternoons off. D) They might leave an hour early on Friday afternoon.
