## Step 1The sentence is discussing the limitations of electromagnetic traps for atomic ions. It states that these traps work well for experiments using a small number of ions, but they are completely impractical for large-scale systems. The conjunction that needs to be inserted should express this contrast between the two situations.## Step 2Let's analyze each option:- A. "so long as" implies a condition, which doesn't fit the context of the sentence.- B. "now that" implies a point in time, which is not relevant here.- C. "although" introduces a contrast, which fits the context of the sentence.- D. "in case" implies a precaution or a hypothetical situation, which is not relevant here.- E. "whether" is used to introduce alternatives, which is not relevant here.## Step 3Based on the analysis, the correct answer is C. "although". It introduces the contrast between the two situations: electromagnetic traps working well for small-scale systems and being impractical for large-scale systems.
