The official has declared the election inconclusive.

Step 1: Analyze the question The underlined word is inconclusive. We need the option closest in meaning to it.

Step 2: Explain the concept Break the word down:

• in- = not
• conclusive = settling a matter, final, decisive

So inconclusive means not final, not decisive, not leading to a firm result. In Nigerian elections, an election is declared "inconclusive" when no winner can be announced yet, for example when the margin of victory is smaller than the number of cancelled votes, so a supplementary election is needed.

Step 3: Test each option

• A. clear: This is the opposite. A clear result is decisive. ❌
• B. satisfactory: This means acceptable. It says nothing about whether a result was reached. ❌
• C. indeterminate: This means not settled, not definitely determined. It matches "inconclusive" closely. ✅
• D. perfect: This means flawless. It has no link to the meaning. ❌

Step 4: Answer The correct option is C. indeterminate.

Step 5: Exam tip When you meet a word with a prefix like in-, un- or non-, strip it off first. Find the meaning of the root (here, conclusive = final), then reverse it. Then eliminate any options that match the root's meaning, like "clear" here, since they are the opposite of what you need.
