While search engines are continuously expanding their reach, copyright law has largely failed to adequately respond to these technological advancements. Rather, the current situation is one of rigid, outdated copyright laws being applied to online activities, which were never contemplated when the original legislation was drafted – causing great ambiguity. Search engines have the crucial role of ensuring the free flow of the internet’s core purpose – access to information. However, by their very nature, copyright laws fundamentally challenge this concept of a freely flowing and accessible internet.
Which of the following statements regarding copyright law is correct?
When answering reading comprehension questions look for keywords and phrases that indicate the type of information you should find in the passage as you read the questions. A keyword or phrase such as "main idea," "supporting evidence," "according to the author," or "in contrast to" can help you focus on the relevant parts of the passage and avoid getting distracted by unnecessary details.
