Directions (79-83): Each of the following questions consists of a paragraph, which may contain one or more grammatical errors. Read the given paragraphs carefully, and then decide how many errors each paragraph contains.

Technology has revolutionized the way we live, work, and communicate in the modern world. From smartphones and social media to artificial intelligence and robotics, technology has transformed virtually every aspect of our lives. While technology have brought many benefits, it has also created new challenges and concerns. As technology continues to evolve, it is important for individuals and society as a whole to consider the ethical and social implications of their use.

The correct answer is Two errors.

Let's analyze the paragraph step-by-step to identify the grammatical errors:

1. Subject-Verb Agreement Error:
In the clause "While technology have brought many benefits...", the subject is "technology", which is a singular noun. Therefore, the helping verb must also be singular. "have" should be replaced with "has". The corrected clause is: "While technology has brought many benefits...".

2. Pronoun-Antecedent Agreement Error:
In the final sentence, "...to consider the ethical and social implications of their use.", the pronoun "their" is used to refer back to "technology". Since "technology" is a singular noun, using the plural pronoun "their" is grammatically incorrect. It should be replaced with the singular possessive pronoun "its". The corrected clause is: "...to consider the ethical and social implications of its use.".

Therefore, the paragraph contains exactly two grammatical errors.
