10. The work of mathematician Roger Penrose in the early 1970s, on the geometry of what are called aperiodic tiles, turned out to describe the architecture of a previously unknown class of crystals.
(A) what are called aperiodic tiles, turned out to describe
(B) what is called aperiodic tiles, describes
(C) aperiodic tiles, describing
(D) so-called aperiodic tiles, describe
(E) aperiodic tiles, it turned out to describe

请问what后面的谓语单复数怎样定？看宾语tiles吗？

turn out 在此题有什么作用，可省略吗？因为用一般现在时describs表示事实或科学真理不是挺好吗？
