Epidemiology is the area of healthcare that deals with the incidence, distribution, and possible
control of diseases, illnesses and other factors relating to health. It is a field where trained
epidemiologists study patterns of frequency and the causes and effects of diseases in human
populations. Epidemiology provides the scientific footings for evidence-based medicine and allows placement of strategies for improvement in public health. This field is often referred to as the cornerstone of modern public health research and practice and it relies on a variety of relevant public health areas, including biology, biostatistics, social sciences, and assessing risk of exposure to a threat.

Epidemiologists study outbreaks of diseases, the causes, locations, and how various
communities are affected, utilizing relative information to aid in the prevention of future outbreaks. These people help to keep the public informed of methods to maintain and improve public health. They work at universities and for government organizations including the (CDC) Centers for Disease Control, National Institute of Health (NIH), or the World Health Organization (WHO). The Bureau of Labor Statistics states that epidemiologists earned an average of $65,270 in 2012 with the top ten percent of epidemiologists earning at least $108,320.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

Have you ever thought about having a job where you help come up with new ways to feed
people? The job of food chemist involves studying the components that make up our food at the
molecular level and using that knowledge to improve the preparation, processing, storage and
distribution of processed food. A flavour chemist creates new artificial flavours and foods that are cheaper and easier to produce than natural products, while other food chemists work on ways to avoid food-based diseases. It's a dynamic job that reflects many of the challenges faced by today's food industry.

Food chemists use their scientific knowledge to breakdown the content of food to determine
its chemical makeup. They work in laboratories, offices and in the field on farms and in food
processing plants, coming up with new food sources, as well as ways to preserve natural foods
while keeping them healthy, flavorful and safe to eat. They use chemicals to create flavor blends for food and beverage products in order to enhance or mask the natural flavors. They also employ chemistry to mimic the effects of the cooking process to improve taste.

According to the Bureau of Labor Statistics, the minimum education requirements for
agricultural and food scientists include a bachelor's degree in their specialty from an accredited
college or university. Coursework may include food chemistry, as well as food engineering and
processing, with internships and research encouraged even at the undergraduate level. Many food scientists hold advanced degrees. An advanced degree in a related field, such as chemistry or biology, may qualify for some food science jobs.

The Bureau of Labor Statistics reports that the majority of food scientist jobs are in food
manufacturing where they help manufacturers ensure that food products satisfy safety regulations while satisfying customers' tastes. Other food scientist jobs are found at colleges and universities, within government agencies and with consulting services.

A. Feeding people molecules of food at different levels
