Rationale

Computers automatically change the time settings when DST is established.

The article mentions that many computer-based systems can adjust their clocks automatically, although this process can be limited and error-prone, particularly with changes in DST rules. This indicates that automated adjustments do occur, supporting the validity of this statement. A) The article does not provide evidence that people adjust easily to the time change related to DST. In fact, it implies that the practice of shifting time presents complications, suggesting that adjustment may not be straightforward for everyone. B) As stated in the article, many computer-based systems have the capability to automatically adjust their clocks when DST is established, although this can sometimes lead to errors. This reflects the reality of modern technology's adaptation to time changes. C) The article does not specifically mention how pets or other animals respond to the time change associated with DST. While it discusses the challenges faced by people and systems, it does not provide information about animal behavior. D) The text argues that the original purpose of DST, which was to reduce evening usage of incandescent lighting, is now outdated due to modern energy use patterns. It explicitly states that incandescent lighting is no longer a major source of electrical usage in today's context. Conclusion The rationale behind the correct answer emphasizes the ability of computers to adjust automatically to DST changes, despite potential errors. Other options fail to align with the information presented in the article, either misrepresenting human or animal adaptability or inaccurately portraying the relevance of incandescent lighting in contemporary energy consumption. Thus, the complexities surrounding DST warrant consideration for its abolition, as expressed by the author.
