关于第一篇的C选项：intricate geometric patterns painted in black on white slipped surfaces.
In some cases, a new design was imposed over an earlier one. 这里只提到了intricate patterns被描绘在白色的surface，但并没有指出这种修改比原来的更加精美。如果原文词句为“more intricate...”会更符合C选项。而A选项在原文中有一一对应的句意，因此应该选择。

1.According to one hypothesis, the planet’s gravitational field tugs on the protoplanetary disk of dust and gas from which it formed. The disk exerts its own gravitational tug, and this interplay of forces robs the planet of momentum in its orbital path, forcing it to spiral in toward the star.
2.According to another hypothesis, the planet’s gravitational field is so strong that it creates a groove in the disk, partitioning it into inner and outer regions; the resulting gravitational interactions between the planet and these regions cause the planet to lose orbital momentum and spiral inward.
红色部分是没有同时出现的。
黑体部分是两个假设都出现的元素，C中提到的disk作为一个由气体等组成的元素出现了两次，但是分成两层的disk只出现在第二个假设中。
