Why the other options are wrong:

• long-term climate trends in western Canada.: Long-term climate trends in western Canada are not the topic.
• improvements to snow-removal equipment in Alberta cities.: Improvements to snow-removal equipment are not the main subject.
• airport staffing shortages during winter storms.: Airport staffing shortages are not discussed - only possible flight delays.

Correct Answer: heavy snowfall combined with strong winds.

Why this is correct: The transcript says 25 to 40 centimetres of snow is expected along with wind gusts reaching 90 kilometres per hour. This combination of heavy snow and strong winds will create near-zero visibility.

Why the other options are wrong:

• dense fog and above-average temperatures.: Dense fog and above-average temperatures are not mentioned - temperatures are dropping sharply.
• freezing rain followed by rapid warming.: Freezing rain followed by rapid warming is not described.
• light snow with calm conditions.: Light snow with calm conditions is the opposite of what the report describes.

Correct Answer: avoid unnecessary trips on major highways.

Why this is correct: The transcript says the Alberta RCMP is urging residents to avoid non-essential travel, particularly along Highway 2 and secondary rural roads. They want people to stay off major highways unless it is necessary.

Why the other options are wrong:

• report all minor collisions immediately.: Reporting all minor collisions immediately is not what the RCMP advised.
• travel only during daylight hours.: Travelling only during daylight hours is not the advice given.
• use public transit instead of driving.: Using public transit instead of driving is not mentioned as RCMP advice.

Correct Answer: the mayor of Lethbridge.

Why this is correct: Lethbridge Mayor Blaine Hyggen said the city has pre-positioned equipment but warned that response times could be slower if winds intensify. He made this cautionary statement about potential delays.

Why the other options are wrong:

• a spokesperson for Calgary airport.: The Calgary International Airport statement concerns possible flight delays, not municipal response times.
• an Environment Canada meteorologist.: An Environment Canada meteorologist discussed the weather system, not city response times.
• an Alberta RCMP officer.: The Alberta RCMP gives travel warnings; the response-time caution is attributed to the mayor of Lethbridge.

Correct Answer: cautious and strongly advisory.

Why this is correct: The report provides detailed warnings about the storm and gives strong advice about preparing emergency kits and checking on neighbours. The tone throughout is cautious and strongly advisory.

Why the other options are wrong:

• optimistic and reassuring.: The report is not optimistic or reassuring - it warns of a serious storm.
• light-hearted and informal.: The report is serious throughout, not light-hearted or informal.
• critical of municipal preparedness.: The report describes municipal preparedness positively, not critically.
