causal (for this reason) Doctors think vitamin C can be useful in treating the symptoms of some common illnesses.
Evaluate
Our job on these questions is to combine claims in order to derive some synthesis, and we primarily look for clues based on Causal, Comparative, Pivot or Conditional wording.
The Causal Connector "for this reason" is giving us a big hint that this question wants us to spell out the logic of this causal connection.
If I said, , what can we infer from the connection between the first thing and the second thing?
The most reasonable suspicion is that, . At a minimum, we can supportably infer,
In this example,
"Vitamin C" is the Overlapping Ingredient in both claims. The way that a synthesis usually works is that we remove the overlap and combine the one-offs.
Combining A is B with B is C gives us A is C
The synthesis removes the overlapping B and ties together the one-offs of A and C.
Combining Kim likes Lebron with so, Kim won't like my tweet gives us my tweet relates to Lebron
The synthesis removes the overlapping Kim and ties together the other two ideas.
Goal
Combining Vitamin C helps us with collagen with so, Vitamin C could help with symptoms gives us symptoms relate to collagen
Let's look for something like .
