Which is the best use of punctuation?
a. pole vaulting—and shot put—are olympic track and field events.
b. the industrial revolution (a period between 1750 and 1850) brought many changes to manufacturing.
c. students will study economics, and history throughout the course.
d. the show (was a spectacular event) that people will remember for many subsequent years.

The right option is; B. The Industrial Revolution (a period between 1750 and 1850) brought many changes to manufacturing.

Punctuation is the system of using points or marks in writing, inorder to separate sentences and their elements and to interpret their meaning. Examples of punctuations include bracket [ ], comma (,), apostrophe (’), colon (:), dash (‒), exclamation mark (!), full stop (.) and question mark (?).

The sentence the uses punctuation properly is letter B) The Industrial Revolution (a period between 1750 and 1850) brought many changes to manufacturing.

Explanation:

The sentence in letter B uses parentheses appropriately. They are employed to add a non-essential explanation about the Industrial Revolution. Non-essential means that, if we take such explanation away, the sentence will still make sense: The Industrial Revolution brought many changes to manufacturing.

Letter A is incorrect because it uses dashes unnecessarily. Dashes have a similar function to parentheses. In letter A, they were used to isolate an essential piece of information, a part of the subject, which is an incorrect use.

Letter C uses a comma to separate only two items in a list. If there were three items or more, the comma would be necessary. In this case, it isn't.

Letter D has a similar problem to letter A. It uses parentheses to isolate the subject's predicate, which is an essential part of the sentence. That's why it is incorrect.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
