Complete the sentence: The results were inconclusive; ____, further research is needed.

  • A. however
  • B. therefore
  • C. in contrast
  • D. for example

Explanation

Inconclusive results logically lead to the need for more work, so a consequence connector is required. However and in contrast both signal opposition, which does not fit the relationship between the two clauses. For example would introduce an illustration rather than a conclusion.
