Select the punctuation mark that needs to be added to this sentence. my car is broken therefore, i have to ride the bus this week. a. semicolon b. colon c. no punctuation mark is needed. d. comma

A. Semicolon.

Explanation:

My car is broken therefore, I have to ride the bus this week.

In the above provided sentence, there are two independent clauses joined by the conjunctive adverb 'therefore'. This conjunctive adverb acts as both the conjunction for the two independent clauses as well as an adverb.

Semicolons are used to join sentences, especially independent clauses but in cases like this, there is a conjunction in the sentence.While the use of the comma after 'therefore' is correct, it is also mandatory to use a semicolon after the first independent clause. Also, conjunctions in a sentence should be deleted when used between two independent clauses, but the exception here is that the conjunction used in this sentence is a conjunctive adverb. Instead of removing the conjunction, the semicolon will also be added to the sentence alongside the conjunction.

Thus, the final answer will be

My car is broken; therefore, I have to ride the bus this week.

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.
