In comparison to the standard typewriter keyboard, the EFCO

Hi bagdmba,

Thank you for your query. Please find below my comments on your analysis that:

B clearly says that EFCO is either as expensive as standard keyboards or less expensive than standard keyboards...hence, it follows that there will be NO immediate reduction of typing costs. Either typing cost will remain same or will go up. So, why B is discarded?

My comments: First of all, choice B, if anything, is in the opposite line of thought than our job in this question. The question stem asks us to WEAKEN the conclusion that the replacement of standard keyboards with EFCO keyboards will result in immediate cost reduction. However, choice B states that EFCO keyboards require less frequent repair than do standard keyboards. This suggests that there is going to be a reduction in the operating costs of keyboards if we follow the author’s suggestion. Moving on, choice B only talks about the manufacturing costs of the two types of keyboards. We can’t conclude much about the price of a product from its manufacturing cost. At best, this information could only vaguely indicate that there is not going to be much difference between the one-time acquisition cost of an EFCO keyboard and that of a standard key-board. This understanding, combined with the lower operating costs of EFCO keyboards, goes on to show the merits of the author’s suggestion. Clearly, option B does not weaken the author’s logic in any way.

Choice D on the other hand, addresses the immediate cost reduction bit in the conclusion. It states that there are additional costs involved in going through with the replacement and these costs will have to be incurred rather immediately. Hence, it is the correct weakening choice.

Hope the above analysis helps .
