Fact, Opinion and Author's Bias Flashcards

"The Pacific Ocean is the largest and deepest ocean on Earth, covering about 165 million square kilometers. Anyone who hasn't sailed it doesn't truly understand the planet's scale." Question: Which sentence is a fact?

Answer: The Pacific Ocean covers about 165 million square kilometers and is the largest and deepest ocean.

Ocean size can be measured and verified; the claim about understanding 'the planet's scale' requires sailing is an unverifiable personal judgment.

A school newsletter reads: "This year's science fair had 142 student participants, a record high. The projects covered topics from robotics to botany. It was undoubtedly the most impressive science fair any school in this district has ever hosted." Question: Which statement is an opinion?

Answer: It was undoubtedly the most impressive science fair any school in this district has ever hosted.

'Most impressive ever hosted in the district' is a comparative superlative judgment that cannot be objectively measured across all past fairs.

A book on nutrition states: "The Mediterranean diet emphasizes vegetables, legumes, whole grains, and olive oil. Multiple long-term studies link it to reduced risk of heart disease and longer lifespan. The Mediterranean diet is simply the ideal way for all humans to eat." Question: Which sentence is an opinion?

Answer: The Mediterranean diet is simply the ideal way for all humans to eat.

Study links and dietary components are verifiable; 'ideal way for all humans' is a prescriptive universal claim that studies cannot prove for every individual.

An article critical of social media reads: "Research shows that teenagers who use social media more than three hours daily report higher rates of anxiety. Social media companies are reckless, immoral organizations that care only about profit and are destroying the mental health of an entire generation." Question: What is the author's bias?

Answer: The author is strongly hostile to social media companies and uses emotionally charged language that goes beyond what the research states.

The research finding is reasonable, but 'reckless, immoral organizations' and 'destroying an entire generation' are inflammatory, unsupported characterizations that signal strong negative bias.

"The Wright Brothers made the first successful powered airplane flight at Kitty Hawk, North Carolina, in December 1903. Their flight lasted 12 seconds and covered 37 meters. Aviation is the greatest gift technology has ever given to humankind." Question: Which sentence is an opinion?

Answer: Aviation is the greatest gift technology has ever given to humankind.

Duration, distance, location, and date are recorded historical facts; 'greatest gift to humankind' is a subjective comparison of all technological developments.

A political commentary reads: "The new highway bill allocates $80 billion for infrastructure repairs over ten years. The opposition party voted against it unanimously. Clearly, the opposition does not care about the safety of ordinary citizens." Question: What technique reveals the author's bias?

Answer: The author infers the opposition's motivations ('does not care') from a voting record without considering other explanations for the vote.

Voting against a bill can reflect disagreement with its funding mechanism, cost, or riders — not necessarily indifference to safety; attributing a single motive is a biased inference.

A review of a hiking trail reads: "The trail is 8.5 miles long with an elevation gain of 1,200 feet. It passes a waterfall at mile 4. This trail is the most rewarding hike in the entire state for anyone who loves nature." Question: Which part is a fact?

Answer: The trail is 8.5 miles long with an elevation gain of 1,200 feet and passes a waterfall at mile 4.

Trail distance, elevation, and a landmark's location are measurable; 'most rewarding' is a subjective ranking across all hikes in a state.
