Answer: . b. Admit the monthly maintenance report but not the e-mail.
Step-by-step explanation:
The monthly maintenance report can be admitted because it was done without the extraordinary circumstance of the oil well explosion occurring. This is unlike the email that was only done after the well exploded.
The point it, the regional safety inspector made the maintenance reports without an explosion happening so there is less chance of bias. The email was however sent after the explosion so could be biased in order to avoid a law suit.
