  Reading Material

  An allergy is defined as an "immunological hypersensitivity to a specific external stimulus" or, simply put, an exaggerated response of the immune system to a substance that is foreign to the body. Patients with allergies are called "atopic" or, more popularly, "allergic". The diagnosis of an allergy is mainly clinical and it can be aided by skin allergy tests and laboratory examinations.

  Skin allergy tests are fast, practical, and can be done in an allergy and immunology provider's office. While skin tests are generally sufficient to confirm a diagnosis, doctors may also request complementary laboratory studies for further confirmation. These blood tests may diagnose an increase in white blood cells or antibodies for common allergy triggers, such as pet dander, grasses, and molds. Blood tests may help confirm or exclude the possibility of an allergy and, consequently, reduce adverse reactions caused by unnecessary medication. A correct diagnosis, along with proper treatment based on the valid results of allergy tests, will help reduce or eliminate the incidence of symptoms and improve the patient's quality of life.

  Why is it important to be tested for allergies if they are suspected?

  A. to exclude certain allergies and explore the possibility of others
  B. all of these
  C. to reduce adverse reactions caused by unnecessary allergy medications
  D. to reduce the incidence of allergy-related symptoms
  B. all of these

• Question 509:

  Read the following passage and answer the question.

  DID CESAR CHAVEZ ADVANCE WORKERS’ RIGHTS?

  César Estrada Chávez (1927–1993) was an American farm worker, labor leader, and civil rights activist who, with Dolores Huerta, co-founded the National Farm Workers Association, which later became the United Farm Workers (UFW).

  A Mexican American, Chávez became the best known Latino civil rights activist, and was strongly promoted by the American labor movement, which was eager to enroll Hispanic members. His public-relations approach to unionism and aggressive but nonviolent tactics made the farm workers' struggle a moral cause with nationwide support. By the late 1970s, his tactics had forced growers to recognize the UFW as the bargaining agent for 50,000 field workers in California and Florida. However, by the mid-1980s membership in the UFW had dwindled to around 15,000.

  Chavez was a charismatic, gifted speaker who inspired Latinos to band together and devote themselves to the farmworkers' movement. Claiming as his models Emiliano Zapata, Gandhi, Nehru, and Martin Luther King, he called on his people to "Make a solemn promise: to enjoy our rightful part of the riches of this land, to throw off the yoke of being considered as agricultural implements or slaves. We are free men and we demand justice."

  After his death he became a major historical icon for the Latino community, and for liberals generally, symbolizing militant support for workers and for Hispanic power based on grass roots organizing and his slogan "Sí, se puede" (Spanish for "Yes, it is possible" or, roughly, "Yes, it can be done"). His supporters say his work led to numerous improvements for union laborers. His birthday has become César Chávez Day, a state holiday in eight US states. Many parks, cultural centers, libraries, schools, and streets have been named in his honor in cities across the United States.

  Which of the following is NOT a meaning of the phrase “throw off the yoke of being considered as agricultural implements or slaves”?

  A. Agricultural workers have more value than mere tools
  B. Workers have freedom and rights
  C. Workers should fight to keep their jobs
  D. Workers are more than animals that can be harnessed to do work
  E. Workers should not be treated as economic slaves
  C. Workers should fight to keep their jobs
