不定式的被动式作什么成分

Not SO, say Indian policymakers, pointing to official statements that lament the violence, express support for sovereignty and territorial integrity, and call for diplomacy to be given a chance. Moreover, they say, the abstentions should be seen in the context of India's long tradition of being beholden to no superpower. Yet many of the countries India once claimed to lead in a cold-war era t non-aligned movement" have joined in the condemnation of Mr Putin's actions.

被动问题，这里的to be given a chance表达的意思是？充当什么成分？

这里的to be given a chance可以看作补语，补足说明diplomacy. diplomacy 这里指外交方法或渠道。

英语的原意为：给外交方法一个机会。按汉语的表达习惯，call for diplomacy to be given a chance 等于“倡导通过外交渠道解决”。
