3、nd【C3】_, while the swelling ranks of pensioners will smash government【C4】_.But the notion of a sharp division between the working young and the【C5】_old misses a new trend, the growing gap between the skilled and the unskilled.

5、e to retire early. Longer life, combined with the replacement of generous pension plans【C10】_meaner ones, means that even the better-off must work longer to have a【C11】_retirement.

Researchers have discovered that African Elephants have the largest number of genes【C1 】 _smell of any mammal. Given the size of their trunks, and how important it is【C2】_their
13、survival, it is probably unsurprising that an elephants nose is not only the longest in the animal kingdom, but also the most effective.In【 C3】_, humans and other primates have a poor sense of smell. “The functions of these genes are not well known,【C4】_they are likely important for the living envir
14、onment of African elephants,“ said author Dr Yoshihito Niimura of the University of Tokyo. “【C5】_, an elephants nose is not only long but also superior. “ The sense of smell is【C6】_to all mammals, and they use it for【C7 】_food, finding mates and locating their offspring.In a study published in Genom
15、e Research, scientists【C8】_the 13 mammal species and found that African Elephants have twice the number of smell genes【C9 】 _dogs and five times more than humans. They have around 2,000 genes alone that are associated with scent. Humans in comparison have just under 400 and some other primates even【
16、C10】_. The study found that 20,000 genes are【 C11】_for the sense of smell in mammals, of which around half are functional, but the collections【C12】_for each species. Horses have around 1,000 smell genes, rabbits around 750 and rats about 1,200.“The large repertoire of elephant (smell) genes might be
17、 attributed to elephants heavy【C13】_on scent in various contexts, including social【C14】_and reproduction,“ added Dr Niimura. African and Asian elephants possess a【C15】_scent organ behind each eye, and male elephants can produce a special substance during annual mating, which is characterized【C16】_in
18、creased aggressiveness.
