Identifying Tone Practice Test

Read the passage, then answer: What tone is suggested by the passage?

My grandfather insists that his old radio still works perfectly, which is a bold claim for an object that looks like it survived three separate attics. When I visit, he is already waiting with a screwdriver and the kind of confidence usually reserved for game-show hosts. “We just have to persuade it,” he says, as if the radio has feelings and a stubborn personality.

I sit at the kitchen table while he removes the back panel with exaggerated care. Dust drifts out like it has been saving itself for this moment. He points to a tangle of wires and explains, in a voice both serious and theatrical, that the problem is “obviously” a loose connection. I nod like I understand, although my expertise ends at turning things on.

After several minutes of poking and muttering, he flips the switch. The radio responds with a dramatic hiss, then silence, then—miraculously—a faint burst of music. My grandfather grins as if he has negotiated a peace treaty. I laugh, partly because it is funny, and partly because I feel lucky to witness his stubborn joy.

Later, as the station fades in and out, he tells me stories about listening to late-night broadcasts as a teenager. The radio never becomes stable, but the afternoon does. When I leave, the music is still sputtering, and I am still smiling, thinking that some repairs are less about fixing and more about spending time together.

Read the passage, then answer: How does the author convey tone in the passage?

A team of astronomers reports the detection of a faint exoplanet atmosphere using a refined spectrographic method. The planet, designated Kepler-1649c, passes in front of its star every 19.5 days, allowing scientists to analyze starlight filtered through atmospheric gases. In the latest observation set, the instrument records subtle absorption features consistent with water vapor and carbon dioxide.

The researchers describe the signal as modest rather than definitive. They compare the new measurements with earlier data from two years prior and find a stronger match after correcting for instrument drift. To reduce the chance of false positives, they run simulations that model stellar activity, including starspots that can mimic atmospheric signatures. The corrected results still indicate the same features, though the confidence level remains below the threshold typically required for a formal claim.

The report outlines practical next steps. Additional observations during the planet’s next six transits could increase confidence, especially if the same absorption pattern repeats. The team also notes that alternative explanations, such as thin dust rings, must be examined before concluding that the gases originate from a stable atmosphere. Throughout, the authors avoid dramatic predictions, focusing instead on what the data can and cannot support.

If confirmed, the method would expand the range of planets whose atmospheres can be studied with existing telescopes. For now, the findings are presented as a promising indication that warrants further scrutiny rather than immediate celebration.
