Company president: Whenever you subcontract the manufacturing of a product, you lose some control over the quality of that product.
Statements
conditional (whenever = Left side, sufficient)
Subcontract the Lose some control manufacturing of → over quality of a product that product We subcontract some manufacturing (i.e. we lose some control over the quality of some of our products)
conditional (only = Right side, necessary)
We subcontract They have complete with a company → control over quality of their products
Evaluate
We see two conditional claims, signified by "whenever" and "only". Do they chain together? Is there any Overlapping Idea?
They're both talking about subcontracting, and they're both talking about control over the quality of products. Hmm. Sometimes we need to contrapose a conditional to see how it would fit.
If we contrapose the first sentence is saying,
not lose some control not subcontract over quality of product → manufacturing
Here, we hope that it clicks that "not losing some control over quality" is a match for "maintain complete control over quality". If you've maintained complete control, then you haven't lost any control, and thus you haven't subcontracted.
Goal
Since this company subcontracts, they are losing some control over the quality of their product. Since the companies they subcontract with maintain complete control over quality, those companies do not subcontract.
Maybe the answer will say ?
