Answer:
1. You need to separate these two sentences - <em>Mr. Chakota started</em>... and <em>They were joined</em>... - these are two sentences so there needs to be a period between them.
<em>... and former oDesk colleague Josh Brianlinger. They were joined by...</em>
2. <em>"They're going to get their books from there.</em>" - the words <em>they're</em>, <em>their</em>, and <em>there</em> sound the same but mean different things. <em>They're </em>is short for <em>they are, their </em>means that something belongs to <em>them, </em>and <em>there </em>shows us where something is.
3. <em>Your files are graded on accuracy and formatting AND you're going to need to follow Rev style guidelines.</em> - these are two sentences so you either should add the conjunction AND or separate these two sentences completely by using a period between them.
4. <em>It's important that quality is consistent. </em>- here, you need to use <em>it's </em>(short for <em>it is</em>) instead of <em>its </em>(meaning, belonging to <em>it</em>).
5. <em>Use foreign language tags for foreign language speech... </em>- this sentence doesn't make much sense so you might want to rephrase it completely
6. <em>Please, no iPads, iPhones, </em><em>or </em><em>Android tablets. </em>- here, you need to use <em>or </em>instead of <em>nor</em> because English doesn't support double negatives.
a ruler, temperature, blueprints, maps
A. because most people would have a healthy breakfast like cereal or fruit
