虚心请教 TPO11 Begging by Nestlings

4. Paragraph 2 indicates that the begging calls of tree nesting warblers

○ put them at more risk than ground-nesting warblers experience

○ can be heard from a greater distance than those of ground-nesting warblers

○ are more likely to conceal the signaler than those of ground-nesting warblers

○ have higher frequencies than those of ground nesting warblers

3，4可排除因为与原文相反答案选1 想请教2如何排除是indicate 和infer的关系吗？？？？

个人理解，说树上的小鸟风险大些，与原文有一定的不符。
原文说树上本来就比地上风险小，所以地上的鸟才会为了适应环境begging的频率高等等。所以应该不能直接得出树上的风险就大吧。

话说，我是上来找这篇阅读的最后一个多选题的。为什么It is genetically disadvantageous for nestilings to behave as if they are really hungry when they are not really hungry这个选项是对的呢？

原文最后一段说了小鸟不会在自己不饿的时候乱叫的原因是为了种族的基因延续啊？不存在恶意欺骗的问题啊？
完全搞不懂
有人解答一下不啊
