Answer:
Mexico City is home to more than 150 museums, and several of those, including the Museo Nacional de Antropología, are considered world-class."
Step-by-step explanation:
The error in subject-verb agreement is in the following part of the sentence:
"including the Museo Nacional de Antropología is considered world-class."
The incorrect verb is "is." It should be corrected to "are" to agree with the plural subject "several of those," like this:
"including the Museo Nacional de Antropología are considered world-class."
