The first part of the sentence is in the past tense ("carried"), but the second is in the present ("goes"). These should be kept consistent. Changing "goes" to "went" corrects the sentence's error. The corrected sentence reads, "Margaret carried her dog, which was often clad in a pink and white argyle sweater, everywhere she went."

The verb "checked" is written in the simple past tense, and the following phrase is not coordinated correctly with the rest of the sentence. This can be fixed by turning it into a gerund: "The man peered around the corner, checking to see if the coast was clear."

This sentence switches tense from past ("as he resigned") to present ("thinks") in the middle of the sentence. In the logical timeline of events, these should both be in the past: "As he resigned himself to eating instant noodles for the rest of the month, Alex thought longingly of prime rib."

This sentence uses inconsistent verb tenses. It starts out in the past ("did not understand") and switches to the present ("is relevant"). Changing "is" to "was" corrects the sentence's error. The corrected sentence reads, "Jose did not understand how a lecture on sea turtles was relevant to a course on Middle-Eastern politics."

The second phrase of this sentence is needlessly in the progressive tense. It sounds clearer and more concise to put this in the simple past: "Testing the new model rocket would not be possible since it was a rainy day."

This sentence uses the wrong form of the verb “to be.” Since "being" follows another verb, "raising," it needs to be in the infintive form, "to be." The corrected sentence reads: "Despite his initial skepticism, Rory found the conference on urban chicken raising to be fascinating, informative, and inspirational."

This sentence has a problem with verb tense. Since the first part of the sentence, "After the canoe flipped over and the provisions were lost," uses two past-tense verbs ("flipped" and "were"), the rest of the sentence needs to be in past tense too, since it is describing events that took place at the same time as those described earlier in the sentence. "Are declaring" is in the present progressive tense, so it contains the sentence's error. You could correct the sentence by changing "are declaring" to "declared," yielding the sentence, "After the canoe flipped over and the provisions were lost, the campers declared the trip a disaster."

This sentence uses the gerund "approaching" when the noun "approach" already exists. Changing "approaching" to "approach" clarifies the sentence. The corrected sentence reads, "It can be difficult to hear the approach of cars running on electric engines."

The timeline of verb tenses in this sentence doesn’t quite make sense. Read it out loud and you will probably hear that something is wrong. Since the first half is in the past, the second half should be too. The corrected sentence reads: After attending a workshop on cake decorating, Joe has brought edible works of art to every family gathering.

The correct verb tense would be "make," since the sentence is phrased as a question and is not a declarative statement about something in the past.
