以下是我做 TPO 27 - Crafts in the Ancient Near East 的一個題目

The vast majority of its population remained active in agriculture, even
those people living within the city itself.
But a small segment of the urban society started to specialize in
nonagricultural tasks as a result of the city’s role as a regional center.
Within the productive sector, there was a growth of a variety of specialist
craftspeople.
Early in the Uruk period, the use of undecorated utilitarian pottery was
probably the result of specialized mass production.
In an early fourth-millennium level of the Eanna archaeological site at Uruk
a pottery style appears that is most characteristic of this process, the
so-called beveled-rim bowl.
It is a rather shallow bowl that was crudely made in a mold; hence, in only
a limited number of standard sizes.
For some unknown reason, many were discarded, often still intact,
and thousands have been found all over the Near East.
The beveled-rim bowl is one of the most telling diagnostic finds for
identifying an Uruk-period site.
Of importance is the fact that it was produced rapidly in large amounts
, most likely by specialists in a central location.

The word “intact” in the passage is closest in meaning to
A unsold
B unused
C undamaged
D unpainted

感覺把字詞套進文句當中很多選項都可以成為答案，
請問各位大大要如何在不了解文字解釋的情況下，透過題目的文句來了解這個字的意思?
