Meaning: 'Issued' means to formally give out or distribute something, such as a warning or statement.

Wrong options:

• declared: While 'declared' could fit, it implies a more definitive statement rather than the formal distribution of a warning, making it less appropriate in this context.
• waged: The term 'waged' typically relates to engaging in a conflict or campaign, which does not apply to the context of issuing a warning.
• aligned: 'Aligned' suggests agreement or coordination, which does not fit the action of providing a warning.

Correct answer: forms

Explanation: The verb 'forms' is appropriate here as it indicates the process by which acrylamide is created in certain foods when cooked at high temperatures. It fits grammatically and contextually, as it describes a natural occurrence.

Meaning: 'Forms' means to create or develop something, in this case, referring to the production of acrylamide during cooking.

Wrong options:

• makes: 'Makes' could imply creation but is less precise than 'forms' in this scientific context, which specifically refers to the process of development.
• prepares: 'Prepares' suggests getting ready for something, which does not accurately describe the chemical process occurring in food.
• gets: 'Gets' is too informal and vague, lacking the specificity needed to describe the formation of a compound.

Correct answer: crisping

Explanation: The word 'crisping' is the correct choice as it refers to the cooking method that leads to the formation of acrylamide. It fits grammatically and contextually, indicating an action that should be avoided.

Meaning: 'Crisping' means to make food crispy, often through cooking at high temperatures, which is relevant to the warning about acrylamide.

Wrong options:

• sagging: 'Sagging' refers to drooping or losing firmness, which is unrelated to the cooking process discussed in the context.
• mixing: 'Mixing' implies combining ingredients, which does not relate to the cooking method that produces acrylamide.
• making: 'Making' is too general and does not specifically address the cooking technique that leads to the formation of acrylamide.

Correct answer: alarmist

Explanation: The term 'alarmist' fits well as it describes advice that may cause unnecessary fear or concern. It aligns with the context of questioning the validity of the warning given.

Meaning: 'Alarmist' refers to someone who exaggerates dangers or problems, often causing undue panic.

Wrong options:

• pure: 'Pure' does not fit the context, as it does not relate to the nature of the advice being questioned.
• real: 'Real' implies authenticity but does not capture the essence of the advice being overly cautious or exaggerated.
• fake: 'Fake' suggests something that is not genuine, which does not accurately describe the nature of the advice in question.

Correct answer: conclusive

Explanation: The word 'conclusive' is the best fit as it indicates evidence that is definitive and leaves no room for doubt. It fits grammatically and contextually, emphasizing the lack of strong evidence regarding cancer in humans.

Meaning: 'Conclusive' means providing a final answer or decision, especially in terms of evidence that is decisive.

Wrong options:

• direct: 'Direct' does not convey the idea of certainty or finality that 'conclusive' does, making it less suitable in this context.
• straight: 'Straight' is too vague and does not pertain to the quality of evidence being discussed.
• probable: 'Probable' suggests likelihood but lacks the definitive nature implied by 'conclusive,' which is necessary in this context.
