The passage below is from a test paragraph. In the sentence with underlined “if,” I’m not 100% sure about what is the exact meaning of “if.” At a first glance it seems to mean “evan if,” but I want to ask you of your answer. Thanks in advance. http://www.google.co.kr/url?sa=t&rc...BPltz8mzDpFBYOQ&bvm=bv.49967636,d.dGI&cad=rjt What if you're paying attention to one stimulus and another stimulus in the environment requires your notice? For example, what if you were sitting in the library reading a book and someone shouted, "Is that a fire?" Even though you were paying attention to the book, you would perceive the shout. Indeed, if there were absolutely no processing of stimuli that you were ignoring, you would have to periodically make a conscious decision to monitor your environment to see if anything important was happening: Let's see, is anyone shouting "fire"?
