Blank 4: Explaining the Orange Analogy

This question asks us to choose the most suitable word to fill in the blank (4) in the provided passage. The passage uses an analogy involving a ship sailing away to demonstrate that the Earth is a globe. It then suggests a similar experiment using an orange and a pin.

Let's look at the sentence containing blank (4): "Stick a pin most of the way into an orange, and (4) _________ turn the orange away from you."

The purpose of this action is to observe how the pin disappears from view, just like a ship disappears over the horizon. To effectively demonstrate this curvature effect, the orange needs to be turned in a specific way. We need to consider which of the given options best describes the manner in which the orange should be turned to make the pin disappear gradually, mimicking the ship's disappearance.

Analyzing the Options for Blank 4

We need a word that describes the action of turning the orange. Let's examine each option:

• passionately: This word relates to strong feelings or emotion. It does not describe the physical action of turning an orange.
• accidentally: This implies the action happened by chance, without intention. While one could turn an orange accidentally, the demonstration requires a deliberate action to be effective.
• reluctantly: This means doing something unwillingly. It doesn't describe the manner or speed of the physical action.
• slowly: This word describes the pace of the action, indicating it should be done gradually. Turning the orange slowly allows the observer to see the pin disappear piece by piece, just as the hull of a ship disappears before its mast when sailing away. This matches the observational purpose of the analogy.

Selecting the Best Fit

The analogy aims to show a gradual disappearance due to curvature. Therefore, the action of turning the orange should also be gradual. The word slowly best describes this deliberate, gradual turning action, making the comparison to the ship disappearing over the Earth's curve clear and understandable.

Thus, the completed sentence reads: "Stick a pin most of the way into an orange, and slowly turn the orange away from you."
