What is it about Paris For the last two centuries it has been the single most visited city in the world. Tourists still go for the art and the food, even if they have to brave the disdain of ticket-takers and waiters. Revolutionaries on the run, artists in search of the galleries and writers looking for the license to explore their inner selves went looking for people like themselves and created their own fields filled with experimentation and constant arguments. Would worldwide communist revolution have been conceivable without the Paris that was home to Marx, Lenin and Ho Chi Minh Would Impressionism or Cubism have become "isms" without Paris as a place to work and as a subject to paint How Paris came to be, for such a long time, "capital of the world"
The answer lies in the city’s "myths" according to the distinguished Harvard historian Patrice Higonnet in "Paris: Capital of the World. " In his book, Paris came to stand for
A. Appreciation

Sleep Lets Brain File Memories
To sleep. Perchance to file Findings published online this week by the Proceedings of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzz’s.
Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically, they examined the electrical activity emanating from the somatosensory neocortex (an area that processes sensory information) and the hippocampus, which is a center for learning and memory. The scientists found that oscillations in brain waves from the two regions appear to be intertwined. So-called sleep spindles (bursts of activity from the neocortex) were followed tens of milliseconds later by beats in the hippocampus known as ripples. The team posits that this interplay between the two brain regions is a key step in memory con
A. There is no relation between memory and hippocampus shrinkage.
B. The more hippocampus shrinks, the poorer one’s memory.
C. The more hippocampus shrinks, the better one’s memory.
D. The less hippocampus shrinks, the poorer one’s memory.

Natural Selection
First coined by Darwin, the term natural selection refers to the process at the core of evolutionary theory. Simply put, Darwin believed that every living organism had to struggle to survive and reproduce. By random chance, some individuals in a species would have characteristics that made them better adapted to this struggle than their contemporaries. Such individuals would be more likely to reproduce and pass their characteristics on to their offspring. Over many generations, a series of small differences in characteristics would accumulate, until eventually the creatures that were produced would be so different from their original ancestors that they would constitute a new species. ■
- (A) Although Darwin did not know how variations between individual members of the same species were able to arise in the first place or how such traits could then be passed on from species to species, we now know that this process
A. Scientists are finding the idea that some traits are naturally selected for their benefits to the species increasingly useful.
B. It is widely accepted by the scientific community that individuals that don’t benefit their species are maladaptive.
C. The human tendency towards altruism is one widely accepted example of a trait traditionally associated with natural selection.
D. The controversy over the idea that traits can be selected based on their benefits to species instead of individuals is inevitabl
