Discriminating evidence is a result the competing models predict differently.
共同预测不能区分模型。
If both predict cooling with greater thickness, observing that trend cannot select one.
同厚度换材料才测试两模型的分歧。
Hold thickness fixed and vary material to test their stated disagreement.
符合一个模型的方向不证明其唯一正确；设计达标与机制解释分开。

Pause here and attempt the task before revealing the reasoning.
请先暂停独立作答，再查看推理。
Use the full context on the preceding pages.
结合前面各页的完整材料。
P predicts the same final temperature because it says material is irrelevant.
P 预测最终温度相同，因为它认为材料无关紧要。
Q predicts B lower than A.
Q 预测 B 比 A 低。
The observed 31°C versus 34°C conflicts with P under matched conditions and agrees with Q's direction.
在配对条件下，观测到的三十一度对三十四度与 P 相矛盾，而与 Q 预测的方向一致。
Calibration supports a meaningful difference, but variability and manufacture still require investigation.
校准支持这是一个有意义的差异，但变异和制造因素仍需要调查。

No; both predict the trend.
不能；两个模型都预测了这个趋势。
Compare A and B of equal thickness while holding starting temperature, runtime, power, fit and room conditions constant.
应在厚度相同的情况下比较 A 和 B，同时保持起始温度、运行时间、功率、贴合程度和室内条件不变。
Repeated matched trials should measure uncertainty.
重复的配对试验应当测量不确定性。
The separating variable is material, not the names of the models.
区分两个模型的变量是材料，而不是模型的名字。

Use the full context on the preceding pages.
结合前面各页的完整材料。
It satisfies cost≤5 and final temperature≤35 in the stated tests.
在所说明的测试中，它满足成本不超过五、最终温度不超过三十五度。
Without a matched A result it does not itself separate P and Q, and design feasibility is distinct from explaining the mechanism.
没有配对的 A 的结果，它本身无法区分 P 和 Q；而且设计上可行，与解释其机制是两回事。
Further durability and variation checks remain appropriate.
进一步检查耐用性和变异仍然是合适的。
Return to the task and explain why the method fits.
回到题目解释方法为何适用。
Original practice does not predict an official score. Complete required live or recorded evidence separately.
原创练习不预测官方分数；现场或录音证据需另行完成。
Pause and test yourself. Cover the worked answer, rebuild the answer to the last example in your own words, and name one condition that would change it before you check.
暂停一下，自我检测：遮住示范答案，用自己的话重做最后一个例子的答案，并在核对之前说出一个会改变结论的条件。
