+# --description--
+
+When you add a lower rank heading element to the page, it's implied that you're starting a new subsection.
+
+After the last <code>h2</code> element of the second `section` element, add an `h3` element with the text `Things cats love:`.
+
+<blockquote>
+  <p>Some text in a blockquote</p>
+  <p>
+    Some text in a blockquote, with <code>code</code>
+  </p>
+</blockquote>
+
+# --instructions--
+
+Do something with the `code`.
+
+To test that adjacent tags are handled correctly:
+
+a bit of <code>code</code> <tag>with more after a space</tag> and another pair of <strong>elements</strong> <em>with a space</em>
+
+# --hints--
+
+The second `section` element appears to be missing or does not have both an opening and closing tag.
+
+```js
+assert(
+  document.querySelectorAll('main > section')[1] &&
+    code.match(/\<\/section>/g).length == 2
+);
+```
+
+There should be an `h3` element right above the second `section` element's closing tag.
+
+```js
+assert(
+  document.querySelectorAll('main > section')[1].lastElementChild.nodeName ===
+    'H3'
+);
+```
+
+The `h3` element right above the second `section` element's closing tag should have the text `Things cats love:`. Make sure to include the colon at the end of the text.
+
+```js
+assert(
+  document
+    .querySelectorAll('main > section')[1]
+    .lastElementChild.innerText.toLowerCase()
+    .replace(/\s+/g, ' ') === 'things cats love:'
+);
+```
+
+There should be an `h2` element with the text `Cat Lists` above the last `h3` element that is nested in the last `section` element'. You may have accidentally deleted the `h2` element.
+
+```js
+const secondSectionLastElemNode = document.querySelectorAll('main > section')[1]
+  .lastElementChild;
+assert(
+  secondSectionLastElemNode.nodeName === 'H3' &&
+    secondSectionLastElemNode.previousElementSibling.innerText
+      .toLowerCase()
+      .replace(/\s+/g, ' ') === 'cat lists'
+);
+```
