Abe, Boris, Cal, and David all proposed to Ellie on Friday. Abe proposed at 5, Boris proposed at 6, Cal proposed at 7 and David proposed at 8. Ellie accepted the last of the four proposals. Some clues: 1-the
times may be am or pm. 2Boris proposed before Abe. 3- At lease one suitor proposed between the
proposals of Cal and David. 4-Cal did not propose between Boris and Abe. Whose proposal did Ellie
accept. Explain.

David's

Step-by-step explanation:

David proposed at 8, making him the latest of the four. The question states that Ellie accepted the last of the 4 proposals, so David's must be the one she accepted. All other information in the question is irrelevant.
