Archaeologists studying Bonito phase (ca. A.D. 900-1140) Native American ceramics from Chaco
Canyon, New Mexico, observed that many pots had been altered after firing to revise their
decorative designs--usually, intricate geometric patterns painted in black on white slipped surfaces.
In some cases, a new design was imposed over an earlier one; less often, the original design was
simply covered with white slip. Crown and Wills doubt that the alterations were made to correct
design errors. Many Chaco pots with design errors were left unaltered. Furthermore, when errors
were corrected, revisions were made prior to firing—either by painting directly over the error or
by scraping off designs and applying new slip and paint, which is a less time-consuming method
than repainting and refiring flawed pots.

2. According to the passage, which of the following is true of Bonito phase Chaco pots?
A:Relatively few of them have original designs concealed beneath white surfaces.
B:Relatively few of them were altered after firing.
C:Many of their alterations increased the intricacy of their painted designs.
D:Many of them have some flaw in their shape or structure.
E:Many of them were altered more than once.

答案给的是A,我看了一下应该是对应 “ less often, the original design was simply covered with white slip.”
可是C为啥不对啊,难道back up不是 “intricate geometric patterns painted in black on white slipped surfaces.
In some cases, a new design was imposed over an earlier one”吗? 求问大神,被阅读虐成狗了。。。

Astronomers have had difficulty accounting for certain planets discovered outside our solar system.
They are called hot Jupiters because each is similar in mass to Jupiter, the largest solar-system
planet, but orbits its parent star at a fraction of the distance at which Earth, let alone Jupiter, orbits
the Sun. In the standard, solar-system-based theory of planetary formation, such as a massive
planet could not form so close to a star. So most attempts to explain a hot Jupiter’s existence
envision it forming farther away, then migrating inward. 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. 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. Another question remains: what prevents the
planet from continuing its spiral until it collides with the star?


2. Which of the following elements is part of one but not both of the hypotheses discussed in the
passage?
A:an interplay of gravitational forces
B:a loss of orbital momentum
C:a protoplanetary disk composed of dust and gas
D:a protoplanetary disk divided into two regions.
答案给的D 我觉得C也没问题啊。。

这里问的是哪一个元素 是 假说的一部分但不是全部。

如果选C的话 disk 在两个假说里都有出现 →全部

而D 就在第二个假说中 说道disk partitioning it into inner and outer regions
