for the above question, I have some confusion between the option B and option E.
After skinning over the explanation of option E in OG, I completely agreed with the point mentioned. but I still can't figure out why not B. I consent successful embargo need to be guaranteed by both two terms, but according to the statement of option B which said the embargo was likely to , not said "must", so it indeed would have the opportunity to succeed cause the other condition would likely to meet meanwhile although not mentioned in the option, but anyway, as the circumstance appears mentioned in option B, we should not exclude the likelihood that embargo will be succeed, right?
Another question need to be confirmed, in option E, does the "a blockade of Patria’s ports " equal to "embargo against Patria", I think no, cause "embargo against Patria" need "a total blockade", not just one, so I consider it should be one aspect to deny the option. does my logic be consistent with GMAC's?
