writing question- bb

<p>Because Uranus is nearly three billion kilometers from the Sun and is enveloped by a thick methane cloud layer, this blocks almost all solar radioation.
D. layer, almost no solar radiation reaches the planet
E. layer, it blocks almost all the solar radiation from reaching the planet.</p>

<p>can someone explain why E is wrong? also, please make another sentence similar to this to clarify a lil.</p>

<p>thanks~</p>

<p>Because in choice E, "it" is ambiguous. To what is it referring? The planet or the methane cloud?</p>

<p>Yeah, technically the "it" could even be the sun.</p>

<p>klol ty=]..</p>
