Prepositions in English Grammar

Understanding the correct use of prepositions is crucial for accurate and clear communication in English. Prepositions show the relationship between a noun or pronoun and other words in a sentence. This question specifically tests the use of prepositions related to causes of death and incidents.

Analysing Preposition Usage for Accidents

When discussing someone being killed as a result of an accident, the preposition 'in' is typically used. This preposition signifies being involved within the event or situation. For example:

• Many people were killed in the car crash.
• Thousands of lives are lost in traffic accidents annually.

The phrase "killed in accidents" correctly conveys that the death occurred as part of or within the context of the accident.

Analysing Preposition Usage for Diseases

When someone dies due to a specific illness or disease, the preposition 'of' is the standard and most commonly accepted usage. This preposition indicates the cause or reason for death. For instance:

• She died of cancer.
• He passed away of natural causes.
• Many people die of heart disease every year.

Therefore, "die of diseases" is the correct and idiomatic expression.

Evaluating the Options

Let's evaluate each option based on the correct prepositional usage:

• Option 1: "in, of"
  • "killed in accidents" - This is correct.
  • "die of diseases" - This is correct.
  • Both prepositions fit the context perfectly.
• Option 2: "from, of"
  • "killed from accidents" - While "from" can denote cause, "in" is the more idiomatic and common preposition for deaths occurring during accidents.
  • "die of diseases" - This is correct.
• Option 3: "during, from"
  • "killed during accidents" - "During" implies the time frame, which is acceptable, but "in" is more specific for the direct involvement leading to death.
  • "die from diseases" - While "from" can be used (e.g., "died from injuries"), "of" is overwhelmingly preferred and more idiomatic when referring to the specific disease as the cause of death.
• Option 4: "from, from"
  • "killed from accidents" - As explained, "in" is better.
  • "die from diseases" - As explained, "of" is better for diseases.

Conclusion on Preposition Choice

Based on standard English grammar and idiomatic usage, the most appropriate prepositions to complete the sentence are "in" for accidents and "of" for diseases. This combination ensures the sentence is grammatically correct and flows naturally.

Therefore, the complete sentence should read: "The untimely loss of life is a cause of serious global concern as thousands of people get killed in accidents every year while many other die of diseases like cardiovascular disease, cancer, etc."
