Question

Study the passage given below and answer the questions based on it.

Over the last decade, the classroom has become a laboratory for intelligent tutoring systems. Adaptive learning platforms now analyse each student's responses in real time, adjusting the difficulty of questions the way a skilled teacher adjusts difficulty mid-lesson. Proponents argue that this personalisation ends the tyranny of the single pace: a fast learner no longer waits while the rest of the class catches up, and a struggling student receives hints before frustration hardens into disengagement. Yet sceptics warn that outsourcing pedagogy to algorithms carries hidden costs. A tutor that optimises only for test scores may narrow curiosity into a set of measurable drills, and the data harvested to train such systems raises uneasy questions about surveilling children. The evidence so far is mixed: several large randomised trials report modest gains in mathematics, while reading barely moves. Perhaps the honest conclusion is that these tools are neither saviours nor saboteurs. Like the textbook and the blackboard before them, they amplify the intent of whoever wields them. The decisive factor remains the teacher, who decides whether the machine serves learning or merely efficiency. Which of the following best captures the central argument of the passage?
