A good way to find answers to general reading comprehension test questions is to read the passage, read the question and then scan the text for the answer. General reading comprehension tests focus on assessing understanding of a reading passage.
Grockit.com suggests focusing on the opening and closing paragraphs of long passages, avoiding using outside information to answer the question and avoiding extreme answer choices. After reading the passage and reading and understanding the question, scan the passage for key vocabulary words in the question. Read two to three sentences before and after the keywords in the passage to find the answer.
