Minor point, you shouldn't be using "<XML>" as an element name. It's
reserved.

In your example each Body-Text contains exactly one question and one answer?
If that's always true, then it's easy. I'm guessing that the real structure
is:

<body-text>
  <question/>
  <xxx/>
  <answer/>
  <xxx/>
  <question/>
  <xxx/>
  <answer/>
  <xxx/>
  <question/>
  <xxx/>
  <answer/>
  <xxx/>
</body-text>

This is a particularly knotty kind of grouping transformation. It's easy in
XSLT 2.0 (you can try this with Saxon 7.0):

<xsl:for-each-group group-starting-at="question">
<assessment>
  <question><xsl:value-of select="current-group()/question"/></question>
  <answer><xsl:value-of select="current-group()/question"/></answer>
</assessment>

It's harder with XSLT 1.0, but by no means impossible. I would do it along
the following lines:

<xsl:template match="Body-Text[.='.....']">
<module>
<xsl:apply-templates select="question[1]"/>
</module>
</xsl:template>

<xsl:template match="question">
<assessment>
  <question><xsl:value-of select="."/></question>
  <answer><xsl:value-of select="following-sibling::answer[1]"/></answer>
<assessment
<xsl:apply-templates select="following-sibling::question[1]"/>
</xsl:template>

I'm afraid I've abstracted from the detail of your actual input and output
here, you'll have to sort out the detail yourself. The <distraction>
elements might make the detail a fair bit more complicated than this; the
trick is to select those <distraction> elements whose
preceding-sibling::question[1] is the current question, which you can test
using generate-id().
