My approach to solve 2Please feel free to correct if need be
2. Which of the following actions does the passage most strongly suggest helped the medical products company lower the cost of manufacturing its electronic device?
A. Adding novel high-performance features to the product
=> not done, not mentioned, doesnt lower cost,
eliminatedB. Using the same electronic circuit board designs as its competitors
=> not mentioned in the paragraph about modifying to competitors devices, therefore not strictly true
eliminatedC. Ensuring that changes to the device were invisible to customers
=> (this is what i selected in my actual mock.) Purchasing team identified changes that would be invisible to customer but lower manufacturing cost. Making these changes reduced the costs. Ensuring the changes were invisible in itself didnt reduce costs. Or to eliminate this option we could argue, that if those changes were made and no effort was taken to ensure they would be invisible to the customer, we would still succeed in lowering costs.
wrongD. Redirecting its marketing strategies
=> Not talked about
eliminateE. Scaling back the options given to customers
=> this helped simplify board design. Therefore helped lower the manufacturing costs. Like in option C we cant argue that scaling back initself didnt reduce costs, but simplifying of the circuit board did. As the process of simplification of the board was equal to scaling back the customer option. Therefore
correct.
