SAT I writing question

<p>Is this a grammatical sentence:</p>

<p>The American politician Benjamin Franklin lived between 1706 and 1790, and he was an accomplished inventor, too. </p>

<p>I said it was fine. the writing section is getting on my nerves. </p>

<p>Also; it's fine that I've made like 8 SAT question threads today right? Will someone get mad at me if I make too many? hope not, it sure helps.</p>

<p>Another one:</p>

<p>The ascendancy of iron tools and weapons over bronze ones marks the transition out from the bronze age to the iron age.</p>

<p>I'm deciding between ascendancy of (shouldn't it just be the ascendance?) and out from. Neither seems grammatical. I guess you could say out from though, so I'm putting ascendancy of as the error. Opinions?</p>

<p>I don’t think you need the “too” seeing as the conjunction “and” already emphasizes an additional characteristic of Benjamin Franklin. You also don’t need “he” as it is already implied.</p>

<p>The American politician Benjamin Franklin lived between 1706 and 1790, and was an accomplished inventor.</p>

<hr>

<p>The “to” before “the iron age” is supposed to be “into.”</p>

<p>The ascendancy of iron tools and weapons over bronze ones marks the transition out from the bronze age into the iron age.</p>

<p>if you left out the “he” from “he was an accomplished inventor,” then you would not need a comma after 1790 because “was an accomplished inventor” is not an independent clause</p>
