Question

请大家帮忙分析一下这句话的句子的结构。谢谢！

With all sides presenting their own experts armed with conflicting scientific studies,whom should parents believe?

Answer 1

with引导的分词独立宾语从句做状语，主句是个问句。
With(介词)all sides(主)presenting(分词谓语)their own experts(从句主语)armed(从句谓语) with(介词引出从句宾语) conflicting scientific（宾语的定语） studies（从句宾语），whom（疑问词引导宾语疑问句）should（情态动词） parents（主语）believe（谓语）?
翻译：各方都出示了他们的专家所支持的相互冲突的科学研究结果，父母们应该相信谁呢？

Answer 2

whom，,who的宾格，作believe的宾语 ，With all sides presenting their own experts armed with conflicting scientific studies是后面whom should parents believe的状语
