Why the other options are wrong:

• a labour dispute affecting port workers.: A labour dispute affecting port workers is not mentioned.
• new federal taxes on marine fuel.: Federal taxes on marine fuel are not discussed in the report.
• the decline of cruise tourism in western Canada.: The report describes cruise traffic rebounding strongly in Vancouver and Victoria, rather than a decline in western Canada.

Correct Answer: can cut air pollution significantly but is not fully adopted.

Why this is correct: The transcript says shore power can cut local air pollution by up to 80 percent, but only about 60 percent of visiting vessels currently use it. So the technology works well but is not fully adopted yet.

Why the other options are wrong:

• only works effectively for smaller passenger ships.: The report does not say shore power only works for smaller ships.
• was rejected by port authorities due to high cost.: The report says about 60 percent of visiting vessels currently use shore power. It does not report port authorities rejecting it due to high cost.
• is currently used by all vessels visiting Vancouver.: Only about 60 percent of vessels use it, not all of them.

Correct Answer: stricter rules could push cruise traffic to American ports.

Why this is correct: The economist warned that stricter rules could shift some cruise traffic to US ports if costs rise too quickly.

Why the other options are wrong:

• port workers would oppose changes to docking procedures.: Port workers opposing changes is not mentioned in the economist's warning.
• shore power technology is unlikely to work in cooler climates.: The economist did not say shore power technology is unlikely to work in cooler climates.
• cruise tourism has already peaked in the region.: The economist did not say cruise tourism has already peaked in the region.

Correct Answer: likely require significant investment and higher port fees.

Why this is correct: Chen said expanding shore power would cost close to 90 million dollars and would likely require higher port fees. She supports cruise tourism but recognises the expansion would need a big investment and increased fees.

Why the other options are wrong:

• be funded entirely by the provincial government.: She did not say the provincial government would fund everything.
• eliminate the need for cruise ships in victoria.: She supports cruise tourism, so she does not want to eliminate cruise ships.
• reduce cruise traffic immediately next season.: She talked about long-term investment, not reducing traffic immediately next season.

Correct Answer: balanced but concerned about long term impacts.

Why this is correct: The report presents both the economic benefits of cruise tourism and the health costs of emissions. It gives facts from both sides and notes that potential policy changes are expected. The tone is fair but shows concern about the long-term effects.

Why the other options are wrong:

• strongly opposed to cruise tourism.: The report is not strongly opposed - it also highlights the economic benefits.
• dismissive of environmental data.: The report includes detailed environmental data and takes it seriously.
• celebratory of recent economic growth.: The report is not celebratory - it raises serious health and environmental concerns alongside economic gains.
