-8.1
Step-by-step explanation:

<em>Times </em><em>all </em><em>by </em><em>9</em><em> </em><em>to </em><em>get </em><em>rid </em><em>of </em><em>fraction</em>
<em>
</em>
<em>Take </em><em>2</em><em>1</em><em>.</em><em>6</em><em> </em><em>away</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>
<em>
</em>
<em>Divide</em><em> </em><em>by </em><em>-</em><em>4</em>
<em>
</em>
The correct answer is option e) tempered.
Compared to the tone of Passage 2, the tone of Passage 1 is more tempered.
Passage 1 discusses recycling as a socio-cultural phenomena, whereas passage 2 is a recycling critique.
Therefore, the tone of passage 1 is a little more upbeat than that of passage 2.
As a result, we may determine that tempered is the most appropriate tone for this passage 1.
