A.I. Explanation:

Option 1: "The technology has benefited education sector."

Explanation: The text begins by acknowledging the benefits of technology in education, indicating that it has positively impacted the sector. This aligns with the main idea that technology provides resources for students, even though it also highlights the challenges faced.

Option 2: "Very few students are able to discover the joy of being lifelong readers."

Explanation: The text states that too few students discover the joys of becoming lifelong readers, directly supporting this option. It emphasizes the contrast between the availability of technology and the actual reading habits of students.

Option 3: "Students are not at all struggling to read."

Explanation: This option contradicts the text, which clearly states that many students struggle to read. The phrase 'too many students still struggle to read' indicates that the assertion in this option is false.

Option 4: "The results are positive after all the efforts put by educators."

Explanation: The text mentions disappointing results despite substantial investments in reading technology, which contradicts the idea of positive outcomes. This option misrepresents the overall message of the paragraph.
