lesson 8
punctuating
parenthetical elements
introduction when you want to include a parenthetical element, or a piece of extra information that is interesting but not absolutely necessary, you use punctuation marks to set it off from the rest of a sentence. you can use commas, parentheses, or dashes.

types of punctuation	when to use	example
parentheses	to set off nonessential information or to remind readers of something they may already know	rachel carson (1907 - 1964) did important research on the effects of chemicals on our water supply.
dashes	to add emphasis, set off a new thought, or show a sudden change in thinking	carson — always passionate about nature — was a powerful and persuasive writer. she began her writing by exploring life in the sea — a world unknown to most readers.

guided practice add the punctuation shown in italics to set off the parenthetical information in each sentence.
hint
when a parenthetical element is in the middle of a sentence, be sure to set it off with the same type of punctuation before and after
example:
isabella, also known as izzie, is shy.
not
isabella — also known as izzie, is shy
1 elizabeth blackwell 1821 - 1910 grew up in a time when women were not welcome in many professions. parentheses
2 she thought women would want to see a female doctor rather than a male about their health concerns. commas
3 blackwell was accepted into geneva medical school after being rejected by twenty other medical schools. dash
4 blackwell a determined person became the first woman to graduate from medical school in the united states. commas
5 she later established a medical school just for women dash

Explanation:

The problem is about punctuation for parenthetical elements, which falls under the Arts discipline, specifically in the subfield of Writing (since it deals with sentence structure and punctuation in writing). The task is to apply the correct punctuation (parentheses, commas, dashes) as per the rules given. For example, in the first guided practice sentence "Elizabeth Blackwell 1821 - 1910 grew up...", we use parentheses around the parenthetical info (1821 - 1910) as per the rule for parentheses (to set off nonessential info or remind readers of known info). So the corrected sentence would be "Elizabeth Blackwell (1821 - 1910) grew up in a time when women were not welcome in many professions."

Answer:

For the first guided practice sentence: Elizabeth Blackwell (1821 - 1910) grew up in a time when women were not welcome in many professions. (Applying parentheses as the required punctuation for the parenthetical element "1821 - 1910" as per the rules for parentheses in parenthetical elements.)
