Meaning: 'To help motivate and guide' means to assist in encouraging and directing the sales representatives in their work.

Wrong options:

• wrong_option_1: 'as motive and guide' is incorrect because it lacks the necessary verb form to indicate purpose, making it grammatically incomplete in this context.
• wrong_option_2: 'should motivate and guide' implies a suggestion rather than a definitive purpose, which does not fit the context of establishing goals that are already in place.
• wrong_option_3: 'as helping motive and guide' is awkwardly phrased and does not use the correct grammatical structure to convey the intended meaning.

Correct answer: must perform

Explanation: The phrase 'must perform' indicates a requirement, fitting grammatically as it uses the modal verb 'must' to express necessity. Contextually, it aligns with the idea that service personnel have specific quotas they are obligated to meet, reinforcing the importance of performance in their roles.

Meaning: 'Must perform' means that it is necessary for the service personnel to complete a certain number of service calls within the designated time frame.

Wrong options:

• wrong_option_1: 'can perform' suggests ability rather than obligation, which does not convey the necessary urgency of the quotas.
• wrong_option_2: 'often are performed' is passive and does not directly relate to the personnel's responsibility, making it grammatically and contextually inappropriate.
• wrong_option_3: 'might be performing' implies uncertainty and does not convey the required action, which is essential in this context.

Correct answer: hinges on

Explanation: The phrase 'hinges on' is a metaphorical expression that indicates dependence, fitting grammatically as it correctly links the subject 'the success of the business' with its reliance on sales. Contextually, it emphasizes the critical role that sales performance plays in the overall success of the business.

Meaning: 'Hinges on' means that something is dependent on or determined by something else, in this case, the successful sales of products and services.

Wrong options:

• wrong_option_1: 'is set at' implies a fixed point rather than dependence, which does not accurately reflect the relationship described in the text.
• wrong_option_2: 'lasts until' suggests a temporary condition, which does not fit the context of ongoing business success being reliant on sales.
• wrong_option_3: 'look ahead' does not grammatically or contextually fit as it does not convey the idea of dependence or reliance.

Correct answer: producing what

Explanation: The phrase 'producing what' fits grammatically as it uses the gerund form 'producing' to indicate an ongoing action. Contextually, it aligns with the planning and efforts that go into creating the products that the sales force sells, making it coherent with the overall message of the text.

Meaning: 'Producing what' refers to the act of creating or manufacturing the items that the sales force is responsible for selling.

Wrong options:

• wrong_option_1: 'describing how' does not fit as it suggests an explanation rather than an action related to the sales process.
• wrong_option_2: 'constructing how much' is awkward and does not convey a clear meaning in the context of sales and production.
• wrong_option_3: 'analyzing where' implies a focus on location rather than the products themselves, which is not relevant to the context of sales.
