The question asks for the best word to replace the underlined phrase "hang around" in the given sentence. Let's analyze the context and the options.

Understanding the Sentence Context

The sentence discusses the fragility of wood sculptures:

"However, wood sculptures are vulnerable to decay, insect damage and fire. As a result, they hang around far less often than sculptuers made of more durable materials."

The underlined phrase "hang around" suggests how long the sculptures last or remain present. The sentence compares wood sculptures to those made from more durable materials, implying a difference in their longevity or persistence.

Evaluating the Options

Let's examine each option to see which best fits the context:

• 1. dry out: This describes a physical process that wood can undergo, but it doesn't directly relate to the lifespan or presence of a sculpture compared to others.
• 2. hang around: This is the original phrase. While it can mean to exist or be present for a long time, it's often informal and might not be the most precise term for describing the enduring quality of an artwork.
• 3. survive: This word means to continue to exist or remain active despite potential damage or difficult conditions. In the context of sculptures, it refers to their ability to last over time, especially when compared to items made from less durable materials. This fits the comparison being made.
• 4. stay on: This implies remaining attached or in a fixed position, which doesn't capture the essence of lasting or enduring over time as effectively as "survive" does in this comparison.

Selecting the Best Improvement

The core idea is that sculptures made from durable materials last longer than wood sculptures. The phrase needs to convey this sense of persistence or longevity.

"Survive" effectively communicates that sculptures made from durable materials endure or last longer, implying they withstand the elements and time better than wood sculptures. It creates a clearer and more appropriate contrast regarding the lifespan of the sculptures.

Therefore, "survive" is the most suitable replacement for "hang around" to improve the sentence's clarity and precision.
