Answer :
Assuming that this is referring to the same list of options that was posted before with this question, the most authoritative source would be a primary source.
The options of the question are, A) A Discovery channel program about the Mars Exploration Rover Mission. B) a book about the atmosphere and geology of Venus published in 1959. C) photographs from the Hobble space telescope of Neptune’s moons. D) an article of science from March 2003 about the rings of Saturn.
The correct answer is B) a book about the atmosphere and geology published in 1959.
The least authoritative source for a science Project of about the Solar System is a book about the atmosphere and geology of Venus published in 1959.
The book about the atmosphere and geology of Venus is not recommended for a good Solar System Project because the topic of the book and the date of publishing do not share the most valuable and up to date information for a precise essay. The best recommendation for a source of good information should be the NASA federal agency. The National Aeronautics and Space Administration is the most valid source of information regarding the Solar System .
