Old Faithful, a famous geyser in Yellowstone National Park, erupts with remarkable predictability. Visitors from all over the world gather to watch the geyser shoot boiling water high into the air. [1] Early cameras required long exposure times to capture clear images of moving water. Many of these tourists wait patiently on the wooden boardwalk, cameras in hand, for the next eruption to begin.
Should the writer keep or delete Sentence 1?
- AKeep it, because it provides historical context about the cameras that tourists are using to take photos.
- BKeep it, because it explains why moving water is difficult to photograph.
- Delete it, because it introduces details about photography history that distract from the paragraph's focus on watching the geyser erupt.Answer
- DDelete it, because it contradicts the idea that the tourists are waiting patiently.
Answer
Delete it, because it introduces details about photography history that distract from the paragraph's focus on watching the geyser erupt.
The correct answer is to delete the sentence because it introduces details about photography history that distract from the paragraph's focus on watching the geyser erupt. The paragraph is centered on tourists waiting for and watching the eruption of Old Faithful. Introducing historical details about camera exposure times deviates from this focus, making the sentence irrelevant.
