`  == Cuba's Sentences make no sense ==  ``Cuba normally observes DST from March to October although the precise dates vary. Thus for two years, Cuba stayed on DST throughout the year.``  The ``Thus`` implies that you can connect the facts in the previous sentence to the conclusion in the second... but there's no logical connection between the two. I don't know enough of the facts to figure out what this is SUPPOSED to say, but maybe someone else does?`
