Final answer:
An emphatic sentence typically ends with b. exclamation point to express urgency or strong emotion. The exclamation point makes the end of the sentence the most emphatic place, distinguishing it from periods and commas that end or punctuate less emphatic sentences.
Step-by-step explanation:
An emphatic sentence is designed to capture attention and convey a strong emotion or importance. It often ends with an exclamation point to indicate the urgency or emotional intensity of the statement. Examples include exclamations such as, \"What a mess!\" or urgent commands like, \"Stop! That hurts!\" The use of exclamation points makes the end of the sentence the most emphatic place.
A sentence can end with a period, a question mark, or an exclamation point, depending on the intention behind it. A period generally ends declarative or imperative sentences with a neutral tone, such as \"The administration canceled classes.\" Commas are used within a sentence as a mark of separation to indicate pauses and to separate nonessential and essential information, helping to structure analytical reports and other texts.
It is important to carefully consider the punctuation used at the end of sentences. While periods and commas help to clarify the structure and convey measured tones, exclamation points are reserved for enhancing emotion or significance, thereby drawing the reader's focus to the key message or action required.
In summary, an emphatic sentence typically uses an exclamation point to signal its importance, and is therefore the correct option for the student's question regarding how an emphatic sentence is announced.
