Question 84

Panel refers to a strip of board or other material that forms a section of a wall or door.

In the context of the extract, 'panel' refers to the glass or plastic panes that make up the walls of greenhouses, which protect the plants inside. This definition aligns with option B, indicating a structural component.

A) A type of decorative fabric used for clothing

This option is incorrect because it describes a type of fabric, which does not relate to the context of the extract. The term 'panel' in the extract specifically refers to structural elements rather than decorative textiles.

B) A strip of board or other material that forms a section of a wall or door

This option is correct as it directly correlates with the description of the glass or plastic panes in greenhouses. These panels are essential for creating a controlled environment for plant growth, aligning perfectly with the definition provided.

C) A tool used for gardening

This option is incorrect since it describes a gardening implement rather than a structural component. The extract does not mention any tools but focuses on the structure of nurseries and greenhouses.

D) A piece of software for editing photos

This option is also incorrect as it relates to software rather than the physical structure discussed in the extract. The context of 'panel' here does not pertain to technology or software applications.

Conclusion

The correct answer is option B because it accurately describes the role of panels in the construction of greenhouses, as explained in the extract. All other options fail to relate to the context provided, which emphasizes structural elements rather than fabric, tools, or software.
