Analyzing the Sentence Completion Question
The question asks us to complete the sentence fragment "Many accidents" by selecting the grammatically correct and logical alternative from the given options. This requires understanding sentence structure, causality, and appropriate verb forms, specifically focusing on whether the subject is performing the action (active voice) or receiving the action (passive voice).
Understanding the Relationship: Cause and Effect
The sentence fragment "Many accidents" suggests that 'accidents' are the subject. Accidents are typically the result of something, like careless driving. Therefore, 'careless driving' is the cause, and 'many accidents' are the effect. In a sentence where the effect is the subject, the verb needs to show that the subject is receiving the action (being caused by something). This points towards using the passive voice.
Evaluating the Options
Let's look at each option to see how it completes the sentence "Many accidents..."
- Option 1: cause careless driving.
Completed sentence: Many accidents cause careless driving.
Analysis: This sentence implies that accidents are the cause and careless driving is the effect. This reverses the logical relationship between accidents and careless driving. Grammatically, 'accidents' (plural) would use 'cause' (plural verb), but the meaning is incorrect.
- Option 2: have caused careless driving.
Completed sentence: Many accidents have caused careless driving.
Analysis: Similar to Option 1, this reverses the logical cause-and-effect relationship. Accidents do not cause careless driving.
- Option 3: are caused by careless driving.
Completed sentence: Many accidents are caused by careless driving.
Analysis: This sentence uses the passive voice ("are caused by") and correctly identifies 'careless driving' as the agent causing 'many accidents'. The subject 'Many accidents' receives the action ('are caused'). This is grammatically correct and reflects the logical relationship.
- Option 4: will cause careless driving.
Completed sentence: Many accidents will cause careless driving.
Analysis: This uses the future tense and again reverses the logical relationship. Accidents do not cause future careless driving.
Identifying the Correct Passive Voice Construction
The original sentence fragment "Many accidents" needs a verb structure where "accidents" are acted upon. The active sentence would be something like "Careless driving causes many accidents." To put this into the passive voice, the object ("many accidents") becomes the subject, and the verb changes form (be + past participle), often followed by "by" and the original subject (the agent). The structure is: Subject (receiver of action) + be verb + past participle + (by + agent).
For the subject "Many accidents" (plural) in the present tense, the 'be' verb is "are". The past participle of "cause" is "caused". The agent is "careless driving".
So, the passive construction is "Many accidents are caused by careless driving."
Conclusion
Based on the analysis of the logical cause-and-effect relationship and the grammatical requirement for the passive voice when the subject (accidents) is the recipient of the action (being caused), Option 3 is the only correct choice.
| Option | Completed Sentence | Analysis | Correctness |
|---|---|---|---|
| 1 | Many accidents cause careless driving. | Incorrect causality (accidents cause driving) | Incorrect |
| 2 | Many accidents have caused careless driving. | Incorrect causality (accidents cause driving) | Incorrect |
| 3 | Many accidents are caused by careless driving. | Correct causality (driving causes accidents) and passive voice | Correct |
| 4 | Many accidents will cause careless driving. | Incorrect causality (accidents cause driving) and tense | Incorrect |
The correct option is are caused by careless driving.
Revision Table: Key Grammar Concepts
| Concept | Description | Relevance to Question |
|---|---|---|
| Passive Voice | Used when the subject of the sentence is the receiver of the action, not the doer. Form: Subject + be verb + past participle (+ by + agent). | "Many accidents" (subject) receive the action of being caused. Required for correct sentence. |
| Active Voice | Used when the subject of the sentence is the doer of the action. Form: Subject + verb + object. | The options incorrectly used active voice or reversed the subject/agent. |
| Cause and Effect | Relationship where one event (cause) leads to another event (effect). | Careless driving is the cause; accidents are the effect. Sentence must reflect this accurately. |
Additional Information: Active vs. Passive Voice
Understanding the difference between active and passive voice is crucial for constructing clear and accurate sentences. Here's a quick comparison:
- Active Voice: The subject performs the action. It's usually more direct and concise.
Example: Careless driving causes many accidents. (Subject: driving, Verb: causes, Object: accidents) - Passive Voice: The subject receives the action. It is often used when the doer of the action is unknown, unimportant, or when you want to emphasize the receiver of the action.
Example: Many accidents are caused by careless driving. (Subject: accidents, Verb: are caused, Agent: driving)
In this question, the focus is on the accidents (the effect), making the passive voice the appropriate choice to complete the sentence fragment correctly and logically.
