Answer: D) Most of the adverse effects of acupuncture that have been reported do not derive from the procedure itself, but from proper application.
Explanation:
The main idea of the paragraph is that the problem with acupuncture is not acupuncture or the procedure itself, but the inadequate way this is used by practitioners: "<em>Still, complications have resulted from inadequate sterilization of needles</em> and from improper delivery of treatments." The message of the text is that <em>the adverse effects and the problems created by the use of acupuncture</em> are related to "<em>inadequate sterilization and improper delivery of treatments." </em>
Answer: B. The presence of soldiers in the small town intimidates its inhabitants.
Explanation:
The actions of the soldiers in the town made the townspeople less lively whenever they were around and these actions were deliberately done for that very reason.
The actions of the soldiers in the store where they would look at the customers whilst holding their weapons were deliberate attempts at intimidation and they worked as the customers would leave, less lively than when they came in.
The presence of the soldiers in the town therefore intimidated the inhabitants.
