The adjustable level of the machine teacher indicates both which benefit and limitation?
Answer and explanation
Correct answer: Personalization and technical dependence
The correct answer is C. The mechanical teacher can be adjusted to match a learner’s level, which represents personalization: instruction may be made easier or more difficult according to individual performance. At the same time, the episode shows technical dependence because the machine’s settings and functioning must be managed by people, and an unsuitable setting can cause difficulty rather than genuine understanding. Option A is wrong because adjustment does not create group celebration. Option B refers to printed books and dust, not adaptable instruction. Option D is incorrect because a machine’s adjustable level does not supply human dialogue or empathy. The paired idea is therefore individual convenience alongside reliance on technical systems.
