Analyzing the Sentence for Grammar Errors

Let's carefully examine the given sentence to find any grammatical errors. The sentence is broken down into three parts and a "No error" option. We need to look at each part:

  • (a) The food consumed
  • (b) in the body is converted on
  • (c) into glucose.
  • (d) No error

The sentence talks about how food inside the body changes into glucose.

Step-by-Step Grammar Error Detection

Let's analyze each part to pinpoint the error.

  • Part (a): The food consumed

    This part introduces the subject, "The food consumed". "Consumed" here acts as a past participle modifying "food", indicating the food that has been eaten. This phrasing is grammatically correct in this context.

  • Part (b): in the body is converted on

    This part contains the verb "is converted" which is in the passive voice, correctly indicating that the food is the recipient of the action of conversion. It also includes the phrase "in the body", which specifies where the conversion happens. However, the preposition "on" following "converted" is problematic.

  • Part (c): into glucose.

    This part specifies what the food is converted into. The preposition "into" is correctly used here to indicate the result of the conversion process.

Identifying the Specific Error in Part (b)

The phrase "converted on into glucose" is incorrect. When we talk about something being changed or transformed from one form, state, or substance into another, the correct preposition to use with "converted" is usually "into".

For example:

  • Water is converted into ice.
  • Energy is converted into heat.
  • Sugar is converted into alcohol by yeast.

In the given sentence, food is changing into glucose. Therefore, the correct preposition should be "into", not "on". The structure should be "converted into glucose".

The incorrect preposition "on" is located in part (b) of the sentence.

Correcting the Sentence

The corrected sentence should read:

"The food consumed in the body is converted into glucose."

This correction removes the unnecessary and incorrect preposition "on" and uses the correct preposition "into" to show the result of the conversion.

Conclusion on the Grammar Error

The error lies in part (b) due to the incorrect use of the preposition "on" after "converted". The correct preposition is "into".

Part Text Analysis Error?
(a) The food consumed Subject and modifier are correct. No
(b) in the body is converted on Includes location ("in the body") and passive verb ("is converted"). Incorrect preposition "on". Yes
(c) into glucose. Correct preposition ("into") indicating the result. No
(d) No error Option if no error is found. Not applicable

Based on this analysis, the part containing the error is (b).

Revision Table: Common Preposition Errors

Verb/Phrase Correct Preposition Example Common Error
Convert into Convert water into ice. Convert on, convert to (sometimes correct in different contexts, but 'into' for transformation)
Depend on / upon It depends on the weather. Depend in, depend with
Listen to Listen to the music. Listen at, listen for (different meaning)
Agree with (person)
on / about (topic)
I agree with you. We agree on the plan. Agree to (different meaning), agree in

Additional Information: Prepositions with 'Convert'

The verb "convert" often uses the preposition "into" to show transformation from one form or substance to another, as seen in the sentence about food being converted into glucose.

However, "convert" can also be used with other prepositions depending on the meaning:

  • Convert to: Can be used when changing from one system or purpose to another (e.g., convert miles to kilometers, convert a room to an office) or changing beliefs/religion (e.g., convert to Christianity).
  • Convert from: Used to indicate the original state or source from which something is converted (e.g., converted from liquid to gas).

In the context of chemical or biological transformation of substances, "convert into" is the standard and correct usage.
