Select the appropriate preposition to fill in the blank. Chairs are made ______ wood.

Appeared in: OSSSC Nursing Officer-2023

Explanation

The correct preposition is 'of' because the material the chair is made from (wood) is still recognizable in its final form.
The phrase 'made of' is used when the basic material has not been changed or transformed into a different substance.
For example, a ring is 'made of' gold, and a sweater is 'made of' wool.

Option A: 'Made from' is used when the original material is transformed into a new substance where it is no longer recognizable.
Option B: 'On' is a preposition of place, indicating position on a surface.
Option C: 'In' is a preposition of place, indicating location inside something.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Correct use of prepositions of material ('made of' vs. 'made from') as background academic context rather than a clinical decision trigger.
While this is a grammar question, clear and precise communication is essential in all professional fields, including nursing, for accurate documentation, patient education, and handovers.
Using correct prepositions prevents ambiguity. For example, describing a wound 'on the arm' versus 'in the arm' has very different clinical meanings.
What if? If a nurse wrote that a dressing was 'made from cotton' instead of 'made of cotton,' it might imply the cotton was chemically altered. While the meaning would likely be understood from context, using precise language avoids any potential for confusion.

How to Approach the Question

First, read the sentence and identify the relationship it's trying to express. Here, it's the relationship between an object (chairs) and its material (wood).
Consider the options. 'On' and 'in' are prepositions of place and do not fit the context of material composition.
Now, choose between 'from' and 'of'. Recall the rule: 'made of' is for materials that are still recognizable, while 'made from' is for materials that have been transformed.
Apply the rule: Is the wood still recognizable as wood in the chair? Yes. Therefore, 'of' is the correct preposition.
