[EX Q]: Context: So that people in developed nations maintain a good lifestyle and people in developing nations have the ability to improve their lifestyles, natural resources must be conserved and protected (Figure 1.1). People are researching ways to find renewable alternatives to non-renewable resources. Here is a checklist of ways to conserve resources: Buy less stuff (use items as long as you can, and ask yourself if you really need something new). Reduce excess packaging (drink tap water instead of water from plastic bottles). Recycle materials such as metal cans, old cell phones, and plastic bottles. Purchase products made from recycled materials. Reduce pollution so that resources are maintained. Prevent soil erosion. Plant new trees to replace those that are cut down. Drive cars less, take public transportation, bicycle, or walk. Conserve energy at home (turn out lights when they are not needed). Click image to the left or use the URL below.

[EX Q]: Context: This article needs an improved plot summary. (November 2015) Sidhu (Akshay Kumar) is a lowly vegetable cutter at a roadside food stall in the Chandni Chowk section of Delhi, who consults astrologers, tarot card readers, and fake fakirs despite his foster father Dada's (Mithun Chakraborty) exhortations. When two strangers from China claim him as a reincarnation of war hero 'Liu Shen' and take him to China, Sidhu, encouraged by trickster Chopstick (Ranvir Shorey), believes he will be feted as a hero, unaware of his own recruitment to assassinate the smuggler Hojo (Gordon Liu). Sidhu travels to China with Chopstick. Along the way he meets Sakhi (Deepika Padukone), the Indian-Chinese spokesmodel known as Ms. Tele Shoppers Media, or Ms. TSM, who also appears in China. Her twin sister Suzy, known as the femme fatale Meow Meow, works for Hojo, not knowing Hojo tried to kill her father, Inspector Chiang (Roger Yuan). Sidhu, through a series of accidents, initially eludes Hojo, but Hojo eventually exposes him as a fraud. Thereupon Hojo kills Dada, and Sidhu is beaten and urinated on by Hojo. Injured and disgraced Sidhu vows revenge. He thereafter encounters an amnesiac vagrant, whom he later identifies to Sakhi as Inspector Chiang. Chiang later recovers his memory and trains Sidhu in kung fu. When Hojo again meets with Sidhu, Suzy injures Chiang; but upon seeing Sakhi, betrays Hojo. Sidhu fights Hojo in single combat, eventually using a modified vegetable-cutting technique to overwhelm him. In the aftermath, Sidhu opens a vegetable stall in China, but is recruited to fight for some African pygmies. The film thereupon concludes with the announcement "To be Continued Chandni Chowk to Africa".

[EX Q]: Context: The purpose of this paper is to assess the reliability and validity of the Spanish version of the Davidson trauma scale (DTS-S) and to determine the prevalence and correlates of post-traumatic stress disorder (PTSD) symptoms in a non-clinical random sample of prison inmates. Probabilistic samples of 1,179 inmates from 26 penal institutions in Puerto Rico were selected using a multistage sampling design. Population estimates and correlations were obtained for PTSD, generalized anxiety and depression. The reliability, factor structure, and convergent validity of the DTS-S were assessed. Cross-validation was employed to confirm the results of the factor analyses. Using the cut-offs adopted by the scale's author, 136 (13.4 percent) of the inmates are likely to have current PTSD and 117 (11.6 percent) reach the cut-off for sub-threshold PTSD. Confirmatory factor analysis generated two factors explaining 53 percent of the variance. High reliabilities were obtained for the total scale (=0.95) and for the frequency and severity scales (=0.90 and 0.91). Significantly higher DTS-S scores were found for females (t=2.26, p<0.025), for inmates diagnosed with depression or anxiety (t=2.02, p<0.05), and those reporting suicide attempts (t=4.47, p<0.0001). Findings support that the DTS-S is a reliable and valid measure to assess PTSD symptoms in Latino inmate populations and to identify individuals at risk for the disorder that require confirmatory diagnosis and clinical interventions.
