A scientist needs 12 mL of a solution. They have a bottle with 0.12L in it. Do they have enough?

Rationale

Yes, they have more than what they need.

The scientist has 0.12 liters of solution, which is equivalent to 120 mL. Since 120 mL is greater than the required 12 mL, they indeed have more than enough solution for their needs.

A (Yes, they have exactly what they need) YOUR ANSWER

While the volume of solution is sufficient, the scientist has more than the required amount. Having exactly what they need would mean having precisely 12 mL, which is not the case since they have 120 mL.

B (Yes, they have more than what they need) CORRECT

This choice accurately reflects the situation. The scientist possesses 120 mL of solution, which exceeds the necessary 12 mL, thereby confirming that they have more than enough to meet their requirement.

C (No, they do not have enough) YOUR ANSWER

This option incorrectly states the availability of the solution. Since the scientist has 120 mL, which is significantly more than the 12 mL required, it is clear that this option does not apply.

D (None of the above) YOUR ANSWER

This choice is not applicable since option B correctly asserts that the scientist has more than enough solution. Therefore, there is a valid option available, making "none of the above" an incorrect choice.

Conclusion

The scientist's 0.12 liters of solution, equivalent to 120 mL, exceeds the 12 mL needed for their experiment. Thus, the correct conclusion is that they have more than enough solution available, confirming option B as the right answer. All other choices misinterpret the available volume in relation to the requirement.
