The committee set about making provisional arrangements for the annual conference.

unconditional
abiding
permanent
lasting

The correct answer is: provisional.

Provisional means “intended to be used or accepted for the time being until something permanent is arranged or decided.” In this case, the committee is making temporary arrangements for the annual conference until they can make more permanent plans.

The other options are incorrect because they do not mean “intended to be used or accepted for the time being until something permanent is arranged or decided.”

  • Unconditional means “not limited or restricted by any conditions.”
  • Abiding means “lasting or continuing for a long time.”
  • Permanent means “lasting or continuing for an indefinite or very long time.”
  • Lasting means “continuing for a long time.”

I hope this helps! Let me know if you have any other questions.
