-acts based on experts own personal observation
-facts made known to expert at trial
-facts not known personally but supplied to the expert outside the courtroom and of a type reasonably relied upon by other experts in the particular field (such facts need not be admissible as evidence, but if they would be admissible, the proponent of the expert testimony must not disclose the facts to the jury unless the court determines that their probative value in hlping the jury evaluate the experts opionin substantially outweighs their prejudicial effect )

these r wrong answer choices
common law traditional rules prohibiting ur own witness unless
they were hostile/uncooperative, u were required to call that party by law, or the witness gave surprise testimony that is affirmatiely harmful to the party calling them
foundation for prior inconsistent statement extrinsic evidence
witness must be given an opportunity to explain or deny the statement AND the adverse party is given an opportunity to examine the witness about the statement

-remember that a prior inconsistent statemetn by a hearsay declarant can be used to impeach the hearsay declarant despite lack of foundation
before or after doesnt matter
