The reference to a "larger target" serves primarily to suggest why a A. blue straggler would be more likely to collide and merge with another star than would be a lower-mass star. B. pair of stars would be more likely to encounter other stars than would the typical blue straggler. C. pair of stars would be more likely to interact with other stars than would a single star. D. blue straggler would be more likely to interact with a pair of stars than it would with a third star. E. third star would be more likely to encounter a pair than it would to encounter a blue straggler.
