使用可选内容组 (OCG) 的解决方案链接的多项选择题

我正在为儿子上大学要参加的能力倾向测验准备一些练习题。有许多示例题。纸质书将问题印在书的前面，将答案印在书的后面。翻页不利于理解问题及其答案。这也使得在限时条件下练习变得困难。

我即将设置一本电子书来练习测试。电子书使用和hyperref包创建的可选内容组 (OCG) ocgx2。但是，我无法将正确的多项选择答案的选择与显示解决方案联系起来。MWE 设置如下。

两个问题（Q1 和 Q2）与一段文本相关。每个问题有五个多项选择答案。每个问题都有一个解决方案。每段文本的内容、问题、多项选择答案和解决方案组合都是从外部文件 (DB.csv) 加载的，datatools并以栅格形式显示在页面上tcolorbox。多项选择答案与单选按钮相关联，这些单选按钮用于切换特定答案选项是正确还是错误。可以切换选项旁边的单独框以显示解决方案。

目前，解决方案与多项选择题答案的响应是分开切换的。我试图让解决方案在给出正确的多项选择题答案时切换。例如，问题 1 的正确答案是 D。当按下选项 D 的单选按钮时，我希望解决方案显示在相邻的框中。

因此，我的问题是：当该链接需要经过条件测试（这是正确答案）时，如何通过单击一个 ocg（多项选择答案）来显示单独的 ocg（解决方案）。

这是 MWE 输出的注释图片 在此处输入图片描述

这是 MWE：

答案1

为了在单击正确的选择按钮时同时显示，解决方案框中的文本必须与相应的选择按钮放在相同的 OCG 上。在本例中，这些是1D问题一和2E问题二的 OCG。

请注意，在原始源代码的\arabic{Q}“ ”代码部分中，不会扩展为正确的值。因此，所需的值在下面的代码中是硬编码的。% Solution to question ?

此外，应对不同的问题使用单独的单选按钮组（例如radiobtngrp=Choices-1， ），因为回答问题二不应隐藏对问题一做出的选择。radiobtngrp=Choices-2
