Chlorine is a mainstay in most swimming pools in the United States, and is used to eradicate bacteria. A bacteria-free pool will usually ensure that swimmers won’t contract a serious illness if they spend time in, and possibly ingest, the water.

When chlorine is added to pool water, a chemical reaction occurs whereby the chlorine breaks down into a legion of chemicals that combine to kill bacteria that may be in the water. These chemicals, specifically hypochlorous acid and hypochlorite ion, eliminate bacteria by annihilating and then oxidizing the abhorrent cells. When this chemical reaction occurs, the bacteria are rendered essentially harmless. This chemical reaction doesn’t occur immediately - individual components within chlorine take varying amounts of time to interact with the bacteria, creating an almost time-release-type of kill in the pool water.

Chlorine must be regularly replenished. As they react, the hypochlorous acid and hypochlorite ion combine to create a particular acceptable pH level in the pool water. A pH is a measure of the alkalinity and acidity present; a pH value of 7 represents a neutral value, and 7.4 is the pH value of the human tear. The pH ratio must be regularly monitored to ensure a consistent optimum rate - one usually kept within the spectrum of 7 to 8 as measured by a reliable pH measuring kit.

As the chemicals in chlorine complete their reactions, they break down and are no longer effective in keeping the pool water neutralized. Additional chlorine must be added to water at specific times. Outdoor pools that are in direct sunlight need to have water added more often because the chemical reaction time for chlorine is increased and its effectiveness is reduced in these conditions.

Since the hypochlorite ion is an especially potent chemical capable of fading fabrics and paint, most people are meticulous about rinsing chlorine from potentially affected areas. Although chlorine is inexpensive and widely available, some people find the bleach smell to be repugnant and the distinct aroma present at many swimming pools to be overwhelming. These people may not be able to enjoy aquatic pursuits in those pools that employ chlorine as a cleansing agent. Other people may find that inhaling chlorine at the high levels present around some pools may be difficult to tolerate. Still others may experience skin irritation after swimming in a pool containing chlorine. Although there are other chemicals and compounds available to clean swimming pools, they may be prohibitively expensive or incapable of killing all types of bacteria present in the water.

Was Felix Mendelssohn (1809–1847) a great composer? On its face, the question seems

absurd. One of the most gifted prodigies in the history of music, he produced his first

masterpiece at sixteen. From then on, he was recognized as an artist of preternatural

abilities, not only as a composer but also as a pianist and conductor. But Mendelssohn’s

enduring popularity has often been at odds — sometimes quite sharply — with his

critical standing. Despite general acknowledgement of his genius, there has been a

noticeable reluctance to rank him with, say, Schumann or Brahms. As Haggin put

it, Mendelssohn, as a composer, was a “minor master . . . working on a small scale of

emotion and texture.”

Q. The passage suggests that anyone attempting to evaluate Mendelssohn’s career

must confront which of the following dichotomies?

While most scholarship on women’s employment in the United States recognizes that

the Second World War (1939–1945) dramatically changed the role of women in the

workforce, these studies also acknowledge that few women remained in manufacturing

jobs once men returned from the war. But in agriculture, unlike other industries where

women were viewed as temporary workers, women’s employment did not end with the

war. Instead, the expansion of agriculture and a steady decrease in the number of male

farmworkers combined to cause the industry to hire more women in the postwar years.

Consequently, the 1950s saw a growing number of women engaged in farm labor, even

though rhetoric in the popular media called for the return of women to domestic life.

sectors in the United States following the Second World War differed in which of

Since the Hawaiian Islands have never been connected to other land masses, the great

variety of plants in Hawaii must be a result of the long-distance dispersal of seeds, a

process that requires both a method of transport and an equivalence between the ecology

of the source area and that of the recipient area.

There is some dispute about the method of transport involved. Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii. Yet the results of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses. More probable is bird transport, either externally, by accidental attachment of the seeds to feathers, or internally, by the swallowing of fruit and subsequent excretion of the seeds. While it is likely that fewer varieties of plant seeds have reached Hawaii externally than internally, more varieties are known to be adapted to external than to internal transport.
