A quibble about the phrasing of "Which former Soviet country has a name starting with E?" Estonia was not a country while under Soviet rule; it was a Republic of the Soviet Union. The question should read either "Which former Soviet Republic..." or "Which country formerly under Soviet rule..." to be precise.
No, it isn't, because it isn't a former Soviet country. I think the question is pretty clear and doesn't need to be changed, but JWC's point is accurate from a grammatical standpoint.
The issue is based on whether you view the phrase as "|former Soviet| country" or "former |Soviet country|." You're reading as the latter, I'm reading it as the former.
Palpatine said "Strike me down with all of your hatred and your journey to the dark side will be complete!" Also can Ben Kenobi be accepted because that was his name at the time
Not only the brain, but also the spinal chord consists of gray matter and white matter. I think that answers like "spinal chord" and "central nervous system" should also be accepted.
What doesn't a rock climber use on a free solo ascent? I can think of a few things that might be an answer for this question...an elephant, a lift, punctuation, a flotilla of navel warships. Ask a specific question and get a specific answer.
