switch assessed and implicated

1. The sentence is correct as it is. The word "myriad" is used correctly to mean a large number or countless people.

2. The word "mere" is incorrectly used in this sentence. Instead of "mere," you could use "peril" or "danger" to convey the intended meaning. So the corrected sentence would be: "The villain wants the world to tremble at the peril of the experiment, but I was only interested in its outcome."

3. The word "minutia" is spelled incorrectly. The correct spelling is "minutiae," as it is a plural noun. So the corrected sentence would be: "The scientific article quickly delved into the minutiae of the experiment, but I was only interested in its outcome."

4. The word "implicated" is used correctly in this sentence to mean that the cumulative exam tested the students' understanding of the covered material. Therefore, the sentence is correct as it is.

5. The word "diminutive" is used correctly to describe the figure skater as being small or petite. The sentence is correct as it is.

6. The word "alluded" is used correctly to mean that the diary hinted or suggested an adventure without providing details. The sentence is correct as it is.

7. The word "assessed" is used incorrectly in this sentence. Instead, you could use "implicated" to mean that the suspects were identified or linked to the crime. So the corrected sentence would be: "The suspects implicated in the crime were arrested and charged with conspiracy to murder."

8. The word "asserted" is used correctly in this sentence to mean that the suspect claimed or stated that he had an alibi for the night in question. Therefore, the sentence is correct as it is.

9. The word "extensive" is used correctly in this sentence to convey that the prom preparations require a large amount of effort and involved many volunteers. The sentence is correct as it is.

10. The word "nominal" is used correctly in this sentence to mean that the effort required is small or insignificant. However, the word "one" should be capitalized as it starts a new sentence. The corrected sentence would be: "The effort required is nominal. One only has to complete the brief questionnaire to be entered into the drawing."

Overall, most of the sentences are correct with just a few minor adjustments needed.
