4Considering the challenging conditions in dual star systems that should render planetary genesis virtually infeasible, the presence of planets in such systems has lacked _______ explanation. Astrophysicists Laura Diaz and James Farley illuminated the topic when they employed simulations to identify a sophisticated set of elements that could bolster planetary formation.4 Mark For Review4Which choice completes the text with the most logical and precise word or phrase?A) a prodigiousB) a respectiveC) an impartialD) a straightforward

Which of the following is the best description of the formation of a giant planet with a massive core? (at least as described in the lectures!)

For all we've learned about the sun, our home star remains shrouded in mystery. Now, after seven years of relative calm, the sun is set to become more ______________-and a fleet of sun-gazing spacecraft are ready to watch as it awakens. Those spacecraft are offering scientists an unprecedented chance to study our stormy star and the ways it can affect our cosmic neighbourhood.1Mark for ReviewABCWhich choice completes the text with the most logical and precise word or phrase?AaccessibleBtemperamentalCmysteriousDtransient
