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 sentence by sentence to identify the grammatical errors:

1. "Technology has revolutionized the way we live, work, and communicate in the modern world."
This sentence is grammatically correct. The singular subject "Technology" correctly agrees with the singular verb "has".

2. "From smartphones and social media to artificial intelligence and robotics, technology has transformed virtually every aspect of our lives."
This sentence is also grammatically correct. The singular subject "technology" correctly agrees with the singular verb "has".

3. "While technology have brought many benefits, it has also created new challenges and concerns."
First Error: The noun "technology" is singular and requires a singular verb. The plural auxiliary verb "have" is incorrect here. It should be replaced with the singular verb "has".
Correction: "While technology has brought..."

4. "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."
Second Error: The pronoun "their" is plural, but its antecedent is the singular noun "technology". To maintain pronoun-antecedent agreement, a singular possessive pronoun must be used.
Correction: "...implications of its use."

Thus, the paragraph contains exactly two grammatical errors.
