MASS Test Practice Questions
MASS Reading Comprehension Sample Question
Try answering this question in 50 seconds. That's how long you'll have during the test.
The most important and continually emerging factor for financial firms to operate successfully in extended global markets is their ability to efficiently serve discerning, highly sophisticated, better educated, and more powerful consumers addicted to the ease and speed of technology. Financial firms that do not realize the importance of these customer-oriented traits are wasting their resources and will eventually perish. Businesses that fail to recognize the impact of these consumer-driven transformations will struggle to survive or cease to exist in a newly forged global financial service community that has been forever changed by deregulation.
Companies should not perish if they recognize which of the following consumer traits?
ANSWER

The consumer is described as “discerning,” meaning perceptive.
(A) refers to the company, not the consumer.
(C) is not mentioned.
(D) contradicts the text (consumer is better educated).
Correct answer: (B).
MASS Mechanical Concepts Sample Question
Try answering this question in 27 seconds- that's how long you'll have during the test.
A tube is attached to the left hand side of a connector and another tube is connected to the opposite face. Water enters the system from the left tube, flows freely through the connector, and exits via the right hand tube. At which opening is the water velocity the greatest?
ANSWER
Click to see the full solution to the question.
Because water flows freely through the system, the amount of water entering equals the amount leaving: Qin = Qout.
Flux is calculated using: Q = A × V. Where: A = cross-sectional area. V = fluid velocity.
Since opening 2 has half the cross-sectional area of opening 1, the velocity must increase to keep the same flow rate.
Set the fluxes equal:
A1V1 = A2V2
A·V1 = (A/2)·V2
2V1 = V2
The exit speed is double the entrance speed. Therefore, the correct answer is 2.
