老吾老以及人之老，幼吾幼以及人之幼？ not exactly the direct translation. this means taking care of elderly of others as how you take care of your own, looking after children of others as how you look after your own.

由于相关讨论愈演愈烈，访客有可能在与政府官员会面时针对该议题提问。 1) 由于 is similar to because 2) 相关讨论 is actually a simplified version of 相关（于该议题 the topic) 讨论 (its more like discussion then debate here) 3) 愈演愈烈 literally means there are and more and more heat (in the debate), 烈 can mean 热烈，演 is 演变 evolve, 愈...愈.. means more and more, similar to 越...越 (延烧 is not a chinese word? though I know what you mean) 4) it is more common to say 访客 instead of 访宾 for guest 5) 会见 is more neutral than 拜会， the former can mean meet with each other, while the later always means lower level to higher level. 6) government official is more like 政府官员. On the other hand, 政府高层 means high rank officials 7) 有可能 represents a slightly higher possibility than 不排除, so depends on the context. E.g. if it's about 50%, then 有可能, if it's like 20%, then 不排除 Hope can help a bit~~:)
