The passage below is from a web-site as follows:
http://www.testden.com/public-speaking/Chapter-XXII-Influencing-By-Suggestion.html Most of our opinions and actions are not based upon conscious reasoning, but are the result of suggestion. In fact, some authorities declare that an act of pure reasoning is very rare in the average mind. Momentous decisions are made, far-reaching actions are determined upon, primarily by the force of suggestion.In the last sentence above, I have two questions that comes up to my mind.
? Momentous decisions are made, (and)
far-reaching actions are determined upon, primarily by the force of suggestion.
Should add “and” in the sentence, so it can make a parallel structure. If this case be right sentence “far-reaching actions” should be the object of “upon.” Then, why is “and” omitted? (Am I too picky?)
? Momentous decisions are made, (which)
far-reaching actions are determined upon, primarily by the force of suggestion.
The author leave out “which,” and “far-reaching actions are determined upon” is modifying “momentous decisions.”
Thanks in advance.
