Short Answer 
To identify missing prepositions, analyze the context of the sentence to understand the relationships involved, then select appropriate prepositions based on that context. Lastly, confirm that the sentences maintain clarity and coherence after the prepositions are added.
Step 1: Analyze the Context
To accurately identify the missing prepositions, it is essential to understand the context of each sentence. Context helps in determining how nouns and other elements relate to one another. Look for clues such as:
- What action is taking place?
- Where is it happening?
- What relationships are being expressed?
Step 2: Identify the Appropriate Prepositions
Once you have a clear understanding of the context, pinpoint the specific prepositions that will link the sentences effectively. In the provided examples, the missing prepositions are important for conveying relationships. Here’s what you need to consider for each blank:
- “Excluded from” connects Joe to the bank.
- “Money in” relates to the field.
- “Allowed at” indicates a location for soccer practice.
Step 3: Confirm Sentence Clarity
After filling in the blanks with the appropriate prepositions, read the sentences again to ensure clarity and coherence. Each preposition should enhance the overall meaning and flow of the sentence. Check that:
- All relationships are clearly expressed.
- The sentences make logical sense.
- The intended message is effectively communicated.
