To answer this question, you need to understand the etiquette and norms of email communication. Let's go through each option to understand why it is correct or incorrect:
Option A) Because it takes up more room and makes the email longer - This option is incorrect because typing in all caps does not necessarily make the email longer. The length of an email is determined by the content and not the case of the letters.
Option B) Because it's considered "yelling" - This option is correct because typing in all caps is widely perceived as shouting or yelling in written communication. It can come across as aggressive, rude, or unprofessional. Using all caps can give the impression that you are angry or trying to emphasize your point forcefully.
Option C) Because it's hard to read - This option is also correct because reading large blocks of text in all caps can be challenging. The lack of variation in letter height and shape can make it difficult to distinguish between words and letters, leading to slower reading comprehension.
Option D) Because it's tough on your keyboard - This option is incorrect because typing in all caps does not put any additional strain on the keyboard. The difficulty lies in the perception and interpretation of the text, rather than the physical act of typing.
The correct answer is B) Because it's considered "yelling". This option is correct because typing in all caps is commonly seen as shouting or yelling in written communication, and it goes against the norms and etiquette of email communication.
