title: Adam is thinner than Barbara. Dalton is less thin than Celia. Adam is less thin than Celia
body: <p>Option:</p>
  
  <p><strong>A)</strong> Adam is thinner than Dalton.</p>
  
  <p><strong>B)</strong> Bárbara is thinner than Adam. </p>
  
  <p><strong>C)</strong> Célia is thinner than Bárbara. </p>
  
  <p><strong>D)</strong> Célia is less thin than Dalton.</p>
  
  <p><strong>E)</strong> Bárbara is thinner than Dalton.  </p>
  
  <p>The right response is <strong>C</strong>, but not function in the following code: </p>
  
  <pre><code>adam='a'
  barbara='b'
  dalton='c'
  celia='d'
  
  adam = dalton
  barbara &gt; adam
  barbara &gt; celia
  celia &lt; dalton
  barbara &gt; dalton
  adam &gt; celia
  </code></pre>
  
  <p>Because when I check the option <strong>B</strong>, <strong>D</strong> and <strong>E</strong> is True and <strong>C</strong> is False. </p>
