1.The cartel little(A) opportunities to keep(B) prices at a level that(C) they feel is(D) appropriate.

There needs to be a verb between "cartel" and "little"

2.The computer training covered(A) everything from(B) to making(C) a file to creating a database(D).
The word "to" needs to be deleted.

3.The policeman ordered the suspect(a) to don't remove(B) his hands(C) from the(D) hood of the car.
The verb form after "suspect" should be "not to remove"

4.The future(A) of our(B) company depends(C) the project quickly.(D)
The preposition "on" needs to be inserted after "depends" and "quickly" needs to be deleted.

5.I can tell you if(A) your loan has approved(B) just as soon as(C) the credit report arrives.(D)
The second verb needs to be "has been approved"

The best way I know to find these errors is to read the sentences aloud or ask someone to read them aloud to you.

1.The cartel little(A) opportunities to keep(B) prices at a level that(C) they feel is(D) appropriate.

There needs to be a verb between "cartel" and "little"

In addition, the word "little" needs to be changed to "few"

To identify the word or phrase that should be corrected in each sentence, you need to carefully read and analyze each sentence. Here are the corrections for each sentence and an explanation of how to identify them:

1. The word "little" should be corrected to "few." The correct sentence should be: "The cartel has few opportunities to keep prices at a level that they feel is appropriate." To identify this mistake, you should pay attention to the context and meaning of the sentence. The word "little" means small in quantity or size, while the correct word "few" means a small number of something.

2. The word "making" should be corrected to "made." The correct sentence should be: "The computer training covered everything from making a file to creating a database." To identify this mistake, you should understand the correct verb form needed in the sentence. In this case, the past tense of the verb "make" should be used, which is "made."

3. The phrase "to don't remove" should be corrected to "not to remove." The correct sentence should be: "The policeman ordered the suspect not to remove his hands from the hood of the car." To identify this mistake, you should recognize the correct grammatical pattern. The verb "order" in this context should be followed by the infinitive form with "not" to indicate prohibition or negation.

4. The word "depends" should be corrected to "on." The correct sentence should be: "The future of our company depends on the project quickly." To identify this mistake, you should understand the correct preposition needed after the word "depends." In this case, the correct preposition is "on," which shows the connection or reliance between two things.

5. The phrase "has approved" should be corrected to "been approved." The correct sentence should be: "I can tell you if your loan has been approved just as soon as the credit report arrives." To identify this mistake, you should recognize the correct verb form needed in the sentence. In this case, the passive voice of the verb "approve" should be used, which is "been approved."

To find these mistakes quickly and easily, it is helpful to have a good understanding of grammar rules and common errors. By paying attention to the context, meaning, and grammatical patterns, you can identify the word or phrase that should be corrected. Additionally, practicing and reviewing different grammar rules and examples will improve your ability to spot these mistakes.
