Meaning: 'Accelerate' means to increase the speed or rate of something, in this case, cash flow, implying that the financial director wants to enhance the speed at which cash is received.

Wrong options:

• achieve: 'Achieve' means to successfully reach a desired objective, but it does not convey the sense of increasing speed necessary in this context.
• decrease: 'Decrease' means to make something smaller or less, which contradicts the goal of improving cash flow.
• slower: 'Slower' is an adjective that describes a reduced speed, which is the opposite of what is intended in this context.

Correct answer: point

Explanation: The word 'point' is appropriate as it refers to a specific moment in time, fitting well within the context of discussing unpaid invoices. It is commonly used in financial contexts to denote a particular time frame.

Meaning: 'Point' in this context means a specific moment or stage in time when invoices are unpaid.

Wrong options:

• aspect: 'Aspect' refers to a particular part or feature of something, which does not fit the temporal context required here.
• place: 'Place' denotes a physical location, which is irrelevant when discussing time.
• hour: 'Hour' specifies a unit of time but is too narrow and does not encompass the broader context of time indicated by 'point.'

Correct answer: watertight

Explanation: The term 'watertight' is used metaphorically to describe contracts that are secure and cannot be easily breached. This fits grammatically and contextually as it emphasizes the strength of the contracts being discussed.

Meaning: 'Watertight' means secure and airtight, often used to describe agreements that are robust and cannot be easily challenged or broken.

Wrong options:

• waterproof: 'Waterproof' refers to something that cannot be penetrated by water, which does not apply to contracts in this context.
• traditional: 'Traditional' implies something that is conventional or long-established, which does not convey the necessary strength of the contracts.
• suitable: 'Suitable' means appropriate or fitting, but it lacks the connotation of security that 'watertight' provides.

Correct answer: fail

Explanation: The verb 'fail' fits grammatically and contextually as it indicates the inability to meet an obligation, which is precisely what is being described regarding debtors not paying on time.

Meaning: 'Fail' means to be unsuccessful in achieving a desired outcome, in this case, making timely payments.

Wrong options:

• manage: 'Manage' implies being able to handle or control something, which does not fit the context of not paying on time.
• insist: 'Insist' means to demand something forcefully, which does not relate to the failure to pay.
• persist: 'Persist' means to continue firmly in a course of action, which does not align with the context of not fulfilling a payment obligation.

Correct answer: This is ok

Explanation: 'This is ok' serves as a transitional phrase that acknowledges the situation while introducing a contrasting viewpoint. It fits well within the context of the discussion about debt collection practices.

Meaning: 'This is ok' means that the situation is acceptable, suggesting that while there may be issues, they are manageable.

Wrong options:

• What is more important: This phrase introduces a new point rather than acknowledging the previous statement, making it less suitable.
• In other words: This phrase is used to rephrase or clarify a statement, which does not fit the context of transitioning to a new idea.
• That is to say: Similar to 'in other words,' this phrase is meant for clarification and does not serve the transitional purpose needed here.

Correct answer: undertaking

Explanation: The word 'undertaking' is a noun that refers to the act of taking on a task or responsibility. It fits grammatically and contextually as it describes the action that should be prioritized in the debt recovery process.

Meaning: 'Undertaking' means an act of taking on a responsibility or task, particularly in the context of initiating actions to recover debts.

Wrong options:

• meeting: 'Meeting' refers to a gathering or assembly, which does not convey the action of taking responsibility for debt recovery.
• evaluating: 'Evaluating' means assessing or appraising something, which is not the primary action being discussed.
• assessing: 'Assessing' means to evaluate or estimate the nature or quality of something, which does not align with the proactive approach implied by 'undertaking.'
