Choose the most effective word from the given words to fill in the blanks to make the sentence meaningfully complete. The policy changes were introduced in an _________ manner, without proper planning
Show Hint
Always look for contrasting or supporting clauses in sentence completion questions.
The phrase ``without proper planning'' acts as a direct definition of the word ``arbitrary''.
Step 1: Understand the context. The sentence says policy changes were introduced without proper planning, suggesting the manner was random or based on whim rather than reason. Step 2: Eliminate incorrect options. "Agreeable" and "acceptable" suggest positive reception; "admissible" relates to being legally allowed. None of these fit the idea of lacking planning. Step 3: Select the correct word. "Arbitrary" means based on random choice or personal whim rather than any reasoned system, perfectly describing changes introduced without proper planning. \[ \boxed{\text{arbitrary}} \]
