The passage is about misconception in the minds of data entry workers. They have concluded that they will be replaced by low wage workers for the 100 computers that the company is going to buy. It looks like they have assumed that the computers being bought are similar to the ones they have been working on. If this is actually the case, then their conclusion has strength. But if this is not the case, the conclusion could be doubted.
Also what if we get to know that the company is going to spend more in the future than today by removing these workers. In such a situation ,the conclusion would weaken.
Looking at options :
1) This option tells us about the flexibility of the workers. It adds to their value for sure and testifies that removing them is not a good thing after all for the company. But these talents do not tell us why the company is planning to remove them from work. May be the company doesn't need their talent. Its hard to determine the link between this option and the conclusion. I believe this option is incorrect because it doesn't impact the conclusion in anyway.
2) Orders from customers of the company have increased. I am able to infer that may be that is the reason behind buying more computers and new ones. But then, why to remove the presently employed workers. Unable to decipher the link. Incorrect choice.
3) The recent memoranda is only telling us that now the data entry operators have to do more work. But then why to remove them when you need them more. If we think a little more, we can relate and discover that may be yes, the intention of the company might be to get more people onboard for the increased work load, more so if they come at lower wages. This option strengthens the conclusion mildly.
4) This option increases our belief in what the workers have concluded. If these people were experienced and higher paid than other similar workers in other companies, it is very much possible that the company is planning to reduce its salary costs.
5) If the computers will allow the company staff to do more work with less energy and manpower, it supports their logical decision of removing the data entry workers. In such a case, it is difficult to agree with what the workers have concluded. This option is a possible weaken statement.
Answer should be E.
