In English grammar, syntactic ambiguity (also called structural ambiguity or grammatical ambiguity) is the presence of two or more possible meanings within a single sentence or sequence of words, as opposed to lexical ambiguity, which is the presence of two or more possible meanings within a single word. The intended meaning of a syntactically ambiguous phrase can generally—although not always—be determined by the context of its use.

equipment (n.) the set of necessary tools, clothing, etc. for a particular purpose

在選項裡的equipment沒辦法清楚表達是什麼樣的設備或裝備

ambiguous：含糊不清的；引起歧義的，模棱兩可的；不明確的。　

We need more efficient equipment.
