选项 A、declares
B、argues
C、claims
D、asserts
答案 C
解析 名词辨析题。[C]claims意为“宣称，断言”，它是四个选项中唯一可以用作claim to do的选项，故选[C]。[A]declares意为“宣布，公布”，用法是“declare sth．(to be)”或“declare that…”，意为“宣布某事”；[B]argues意为“争论，争辩”，用法是“argue about／over sth．”或“argue that…”，意为“争论”;[D]asserts意为“断言，坚称”，用法是“assert sth．”或“assert that…”，意为“断言，坚持认为……”。[A]、[B]和[D]在用法上不符合文章要求，因此排除。
