Identify the transition word that best connects the two sentences:

Traditional fossil fuels are finite and release greenhouse gases that destabilize the global climate. _____, geothermal and solar technologies harness boundless energy flows without catastrophic carbon emissions.

Answer and explanation

Correct answer: B. In stark contrast

  1. Step 1: Compare the semantic orientations of both sentences: the first sentence describes polluting, depleting fossil fuels, whereas the second sentence describes clean, inexhaustible renewables.
  2. Step 2: Select the transition establishing strong antithesis: "In stark contrast" highlights the polar opposition between the environmental profiles of the two energy paradigms.
Answer
In stark contrast.
Why not the others: "Furthermore" signals additive points moving in the same evaluative direction; "Consequently" establishes a direct cause-and-effect relationship; "Similarly" indicates analogy or equivalence between identical features.
