Answer to Question 1

3
Rationale: In order to calculate the proper dosage, 0.25 kg must be converted to mg to match the ordered dosage. 0.25kg = 250 mg. 250 mg/5 mL = 140 mg/x; cross-multiply, yielding 250x = 700. Divide both sides by 250, yielding x = 2.8 mL.

Answer to Question 2

Abstinence
Rationale : No contraceptive is 100 effective 100 of the time. The only form of birth control that is 100 effective is abstinence.
