Expression of Ideas practice question

Several materials we now treat as ordinary were once luxury goods. Aluminium, ____ was so costly in the 1850s that samples of it were displayed alongside the French crown jewels.

Which choice completes the text with the most logical transition?

  1. A. for instance,Correct
  2. B. however,
  3. C. therefore,
  4. D. meanwhile,

Answer: A. for instance,

The first sentence makes a general claim; the second gives one specific case of it. Aluminium is an instance, so 'for instance' fits.

Why the other answers are wrong

B. however,
'However' would signal that aluminium contradicts the claim. It supports it.
C. therefore,
'Therefore' would make aluminium's cost a consequence of the general claim rather than an example of it.
D. meanwhile,
'Meanwhile' signals something happening at the same time as something else; no second event is being compared in time.
