Some of the biased reading passages (as in Questions 164, 176, 181., see 
below) contain too many specialized terms. Such jargon of too specific and/ 
or technical a topic requires test-takers to be equipped with background 
knowledge of the given topic. Despite the fact that background knowledge 
constitutes the most fundamental basis of the complex reading processes, it 
is important to maximize the validity and reliability of the test by minimiz-ing the unwarranted influence of background knowledge or technical terms 
on, the reading comprehension test. It is clear that the test results should be 
interpreted not as a function of the test-taker's background knowledge but 
as the performance mainly of their English reading comprehension skills.
