Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
In his training course, Marvin learned how to address customer concerns, fill out budget requests, and setting up a company account. No error
This sentence has a problem with parallelism. The items in its list aren't all formatted in the same way: the first two things that we're told Marvin learns to do in his training course are "address customer concerns" and "fill out budget requests," each of these phrases beginning with an infinitive verb. The third thing that Marvin learns to do is "setting up a company account"; in contrast to the previous two infinitive phrases, "setting up a company account" is unnecessarily conjugated to be in the present progressive tense. Since changing the first two items to be in the present progressive tense (as well as the rest of the sentence to make this work grammatically) isn't an option, the answer "and setting up" contains the sentence's error. You could correct the sentence by changing "and setting up" to "and set up," making the corrected sentence, "In his training course, Marvin learned how to address customer concerns, fill out budget requests, and set up a company account."

It’s a long drive, but I would much rather drive home than bus. No error
In this sentence, the format of the two items being compared does not stay parallel. “Drive” is a verb, and “bus” is a noun. The corrected sentence reads: It’s a long drive, but I would much rather drive home than take the bus.

Although it was easy for Mary to identify the problem, she found it more difficult to communicate with the technical crew and solving it. No error
This sentence has a problem with parallelism. The verbs “communicate” and “solving” should be formatted in the same way, since they are the two things it was "more difficult" for Mary to do. Since only "solving it," and not "communicate," is underlined, "solving it" contains the sentence's error and is the correct answer. The corrected sentence reads, "Although it was easy for Mary to identify the problem, she found it more difficult to communicate with the technical crew and solve it."

It is a more difficult task to learn to type than mastering a simple word processing program. No error
A sentence should be consistent in its use of verb tense, comparisons, and tone. In the sentence above, "to learn," an infinitive, is being compared to "mastering," a present progressive verb. Things being compared should take on the same grammatical form; that means that "mastering" should be changed to "to master" in order for proper parallel construction to be used. The sentence should read, "It is more difficult to learn to type than it is to master a simple word processing program." "To type" is being compared to "to master"; both are in the infinitive form in this revised case.

The spies started to empathize with the man they were watching, and suddenly they wondered if their actions were morally excusable or not being so. No error
This sentence lacks grammatical parallelism. The phrase “not being so” is clunky, and it doesn’t match with the earlier part “were morally excusable.” The corrected sentence reads: The spies started to empathize with the man they were watching, and suddenly they wondered if their actions were morally excusable or not.

The young girl struggled in school growing up, having trouble with adding, spelling, and the ability to read.
The series placed in the underlined portion of the sentence suffers from the problem of not having a parallel structure. All components in such a list need to take the same format. Therefore, "with adding, spelling, and reading" is the correct answer.

I had expected to learn many essential survival skills at the workshop, but instead only how to open a can without a can opener.
This sentence has a problem with parallelism. Since the first part contains a verb, the second part must as well. The corrected sentence reads: I had expected to learn many essential survival skills at the workshop, but instead I only learned how to open a can without a can opener.

When I was much younger I was very energetic, but now I nap often, watch a lot of television, tired, and rarely work out. No error
All of the items in this poor tired fellow's list of activities need to be in the same form. Yet we find three verbs ("nap," "watch," and "work out") and one adjective ("tired"). Thus, the adjective is the odd one out and needs to be changed (to something like "am always tired").

I must admit that your mom's chocolate chip cookies are quite tasty, but they are not as good as my grandmother—hers are the best! No error
When making comparisons you must be careful to compare like things. In this case, the sentence as written makes a comparison between "cookies" and "my grandmother." You want to compare cookies to cookies. You can fix this error by making "grandmother" into a possessive, singular noun, "grandmother's." This way, it is inferred that the subject being spoken about is the speaker's grandmother's cookies, not the speaker's grandmother herself.

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
After school, the children went to the park, to the store, and home. No error
"Home" contains the error in this sentence because parallel sentence structure dictates that each part in a series must use the same type of word and employ the same tense, if the words are verbs. In this case, the first two parts in the series are prepositional phrases ("to the park" and "to the store"), but the third part is a noun "home." Because only part of one of the prepositional phrases is underlined, we can't change them, so we would need to change the noun, "home," to correct the sentence's error.

That performance has been seen by more people than any musical made in the past decade. No error
The word "other" should be included in a comparison of one thing with a group, so the correct phrase is "any other musical" and "any musical" contains the sentence's error.

The class project consisted of forming groups, discussing questions about the novel, and give a presentation in front of the class. No error

At the deli, the sandwiches are very similar to the cafeteria, except they are slightly larger and contain less fat. No error
This is a faulty comparison. "Sandwiches" cannot be compared to a cafeteria. Use "similar to those at the cafeteria" or something like that instead to correct the sentence's error.

It will rain tomorrow, so I will jog in the park, practice soccer, and playing baseball in my backyard today. No error
This is a parallelism error. The verbs "jog" and "practice" begin the parallel elements in the sentence, and they are each in present tense. The verb "playing" should also be in present tense so that it matches "jog" and "practice." So, "playing" should be "play."

The townfell into chaos and confusion; people fled from their homes and running blindly into obstacles. No error
This sentence has a problem with verb tense and parallelism. Since the “fled” and “running” are coordinated with a conjunction, they should be formatted in the same way. The corrected sentence reads, "The town fell into chaos and confusion; people fled from their homes and ran blindly into obstacles."
