Thomas had always struggled with trigonometry, he thought that circles should remain circles and let triangles and squiggles be their own shapes. No error
This sentence is an example of a run-on or comma splice. It has two independent clauses separated only by a comma. One way to fix this is to change the comma to a semicolon; if this were to be done, the corrected sentence would read, "Thomas had always struggled with trigonometry; he thought that circles should remain circles and let triangles and squiggles be their own shapes."

The eldest male dog became awfully selfish during feeding time, he would not even let his own pups get a scrap of food. No error
Two independent clauses that can each stand alone must be separated by either a period or a semicolon, or connected by a comma followed by a conjunction. Because this sentence doesn't include a conjunction like "and" after its comma, it is incorrect. (This error, where two independent clauses are incorrectly connected by a comma, is known as a "comma splice.")

Although he initially refused to go to the cinema, James finally saw the movie, that his friends had recommended. No error
Commas, gramatically speaking, should never be used before or after the word "that." The correct sentence would have: "James finally saw the movie that his friends . . ."
"Had recommended" could be changed to "recommended", for the sake of simplicity, but the comma error is more flagrant.

Perdita the lost princess, was found and raised by a shepherd. No error
Commas should be used to set off the phrase "the lost princess," as it is in apposition to (gives a description of) the subject Perdita, but the sentence still makes sense without it. So, "Perdita the lost princess," contains the sentence's error, and the sentence should read, "Perdita, the lost princess, was found and raised by a shepherd."

The phrase "If you decide to go to the beach" is an introductory phrase, and all introductory phrases need to be set apart from the rest of the sentence by a comma. So, after being corrected, the sentence would read, "If you decide to go to the beach, make sure to wear sunscreen to protect your skin!"

Daisy and her sister, Margot, shared a large family but a special relationship; even among their numerous older and younger sisters, Margot, and Daisy had a special bond. No error
Because the sentence states that Margot is not Daisy's only sister, the commas and which frame her name in "their numerous older and younger sisters, Margot, and Daisy" are incorrect. The comma that sets apart Margot's name at the beginning of the sentence ("Daisy and her sister, Margot, shared") is correctly used, because here, Margot is being specified as Daisy's sister in an appositive phrase that renames "her sister" as "Margot."

Sarah wanted to arrive at the store in time to buy the fresh bread cereal, and chocolate sauce. No error

Bill, Jane and Jared went to the movies every Sunday afternoon; they liked to sit at the back of the movie theatre because it offered the best view. No error
The phrase “Bill, Jane and Jared” should be “Bill, Jane, and Jarred” because the friend’s names are presented as a list. Words, clauses, or phrases in a series should always be separated by a comma. The sentence “Bill and Jane went to the movies” does not require a comma, but adding the third name, Jared, requires a comma between the three names. Be sure to note that there is no comma after the last word or phrase in the sequence.

Mr. Williams has a number of diverse interests, including skateboarding, and playing video games. No error
There should not be a comma between the words “skateboarding” and “and.” In other words, the second part of the sentence should read “including skateboarding and playing video games.” This is because there are only two interests listed. A comma should only be used in lists containing three or more items.

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
By the end of the night, Derrick could tell that all the guests were full, happy and tired; the party had truly been a success. No error
Since the list "full, happy, and tired" has more than 2 items, each item before the last item must be separated using a comma. Inserting a comma after "happy" will make this sentence correct, so the underlined phrase "happy and" must be changed. Note that a semicolon is correctly used to separate two independent clauses from one another in this sentence.
