A. is ; is
B. are ; are
C. are ; is
D. is ; are
答案：
(答案→)A. is ; is
B. are ; are
C. are ; is
D. is ; are
解析：the iron and steel works“那家钢铁厂”，no means of finding“无法找到”，其中的works“工厂”、means“方法”都是单复数同形的名词，还有其他类似名词如species“种类”、Chinese, Japanese等。work作“工作”解时是不可数名词，而作“作品”解时是可数名词，可以与不定冠词连用，有单复数形式，因此“一件不寻常的艺术作品”such an unusual work of art，谓语动词也随work的单复数形式的变化而变化。A是最佳答案。
