Correct answer: conduct

Explanation: The verb 'conduct' is appropriate here as it refers to the act of leading or managing face-to-face business meetings, fitting grammatically in the context of the sentence which discusses actions related to business interactions.

Meaning: 'Conduct' means to organize and carry out an activity, in this case, leading meetings.

Wrong options:

• take: The verb 'take' implies receiving or acquiring something, which does not fit the context of managing meetings.
• show: The verb 'show' suggests displaying or revealing something, which is not relevant to the act of managing meetings.
• extend: The verb 'extend' means to increase in length or duration, which does not apply to the context of conducting meetings.

Correct answer: strain

Explanation: The noun 'strain' fits well as it refers to pressure or stress placed on the environment, aligning with the context of greenhouse gas contributions and their impact.

Meaning: 'Strain' refers to pressure or stress, particularly in relation to environmental impact.

Wrong options:

• stress: While 'stress' could imply pressure, it is less specific to environmental contexts compared to 'strain.'
• pain: The noun 'pain' typically refers to physical discomfort, which does not relate to environmental issues.
• rest: The noun 'rest' implies a state of inactivity or relaxation, which is contrary to the context of environmental impact.

Correct answer: pressure

Explanation: The noun 'pressure' is suitable here as it refers to the urgency or stress associated with time constraints, which fits the context of international travel and meetings.

Meaning: 'Pressure' means the stress or urgency that can affect decision-making or scheduling.

Wrong options:

• leisure: The noun 'leisure' refers to free time or relaxation, which contradicts the context of time constraints in business.
• stable: The adjective 'stable' implies steadiness or lack of change, which does not fit the context of time-related stress.
• measure: The noun 'measure' refers to a standard unit or action taken, which does not relate to the urgency of time.

Correct answer: separate

Explanation: The adjective 'separate' is appropriate as it describes distinct locations, fitting grammatically and contextually in the sentence about bringing people together from different places.

Meaning: 'Separate' means distinct or not joined, indicating that the locations are individual and not connected.

Wrong options:

• great: The adjective 'great' refers to size or importance, which is irrelevant in the context of locations being distinct.
• suspect: The adjective 'suspect' implies doubt or suspicion, which does not fit the context of describing locations.

Correct answer: unrivalled

Explanation: The adjective 'unrivalled' is fitting as it indicates that the transmission quality is unmatched, aligning well with the context of superior technology.

Meaning: 'Unrivalled' means having no equal or match, emphasizing the high quality of transmission.

Wrong options:

• called: The past participle 'called' does not fit grammatically or contextually as it does not describe the quality of transmission.
• suspected: The past participle 'suspected' implies doubt, which does not relate to the quality of transmission.
• tribled: The term 'tribled' is not a standard English word and does not convey any relevant meaning in this context.
