Answer:
The correct answer is A: generosa
Explanation:
The translation of the example above would be:
The English teacher is more generous than the Spanish teacher.
The correct answer is generosa, as this is an adjective which we use to describe the English teacher.
The construction más + adjective + que is used to compare two things by expressing their inequality with the use of an adequate adjective.
As the rest of the words are nouns, they cannot be considered as the correct answers.
conocimiento - knowledge
tolerancia - tolerance
paciencia - patience
