___ the limited sample size, the study offers valuable insights. Which choice is correct?

  • a.Because of
  • b.Despite
  • c.Due to

'Despite' introduces a contrast: the small sample yet valuable insights. 'Because of' and 'due to' would signal cause, which does not fit the contrast.

Connectors & Prepositions

The first experiment failed; ___, the team revised its method. Which choice is correct?

  • a.nevertheless
  • b.for instance
  • c.consequently
  • d.in contrast

'Consequently' signals a result: the failure led to a revised method. 'Nevertheless' would imply contrast, which does not fit the cause-and-effect here.

Connectors & Prepositions

The theory accounts ___ several observations that earlier models could not explain. Which choice is correct?

  • a.for
  • b.to
