Test the clauses before choosing punctuation
PeakSAT | reviewed 2026-10-13

Original example: The sample looked clear___however, the sensor detected impurities. Both The sample looked clear and the sensor detected impurities can stand as sentences. However signals contrast, but it is not a coordinating conjunction. A semicolon before however makes the boundary; the existing comma after it sets off the transition.

Now change the opener: Although the sample looked clear, the sensor detected impurities. Although makes the first clause dependent, so an introductory comma works. The punctuation changes because the structure changes.

Fresh check: Because the first measurement was inconsistent___the researcher repeated the trial. Use a comma because the opening clause is dependent. These are original teaching examples, not official SAT items.

Original example: A team expected a lighter material to be weaker. Tests showed it resisted more force than the original. The result conflicts with the expectation, so Nevertheless fits. Therefore would invent a cause, For instance would introduce an example, and Moreover would add a similar point.

Keep the conclusion narrow. The result describes the tested material, not every lighter material. Transition meaning and evidence scope are separate decisions, and both depend on the exact statements.

Fresh check: The freezer stopped operating overnight. ___ the samples thawed. Consequently fits this cause-and-effect relationship. Predict the relationship before reading the options. These are original teaching examples, not official SAT items.
