Question

A heated discussion arose since the possibility of a computer made from DNA and enzymes is such a controversial subject. A. arose since B. arise because C. arose because D. arose as E. rose as

Short answer

C. arose because

Step-by-step solution

Identify the grammatical context

The phrase in question is 'A heated discussion arose since the possibility of a computer made from DNA and enzymes is such a controversial subject.' The word 'arose' needs to be paired correctly with a connector that denotes the reason for the discussion.

Analyze the options

Review the provided options:A. arose sinceB. arise becauseC. arose becauseD. arose asE. rose asWe need to choose a grammatically correct and contextually appropriate connector.

Evaluate each option

Option A: 'arose since' is incorrect since 'since' can imply time rather than reason.Option B: 'arise because' is incorrect due to tense mismatch.Option C: 'arose because' is grammatically correct and conveys causation.Option D: 'arose as' is less common but could be correct; however, 'because' is usually clearer.Option E: 'rose as' is not correct because 'rose' needs a different context.

Select the correct answer

The best-fit answer must ensure the sentence retains clear meaning and grammatical correctness. The option 'arose because' appropriately denotes the cause of the heated discussion.

Key concepts

grammar context

To understand the grammatical context, we must first recognize the main components of the sentence. The phrase 'A heated discussion arose since the possibility of a computer made from DNA and enzymes is such a controversial subject.' contains a subject ('A heated discussion'), a verb ('arose'), and a reason for the occurrence of the action ('since the possibility of a computer made from DNA and enzymes is such a controversial subject'). In this case, the verb 'arose' needs to be paired with a connector that accurately conveys the reason for the action. This ensures that the sentence makes logical sense and is grammatically correct.

sentence correction

Sentence correction involves identifying grammatical errors and making sure the sentence conveys the intended meaning clearly. In this exercise, several options were provided, but only one was correct:

• Option A: 'arose since' - Incorrect because 'since' can denote time rather than reason.
• Option B: 'arise because' - Incorrect due to tense mismatch; 'arise' is in present tense while 'arose' is past tense.
• Option C: 'arose because' - Correct as it uses the proper tense and denotes causation.
• Option D: 'arose as' - Acceptable, but 'because' is typically clearer for indicating causation.
• Option E: 'rose as' - Incorrect, as 'rose' signifies a different context and does not work with the subject.

The correct answer is 'arose because,' which maintains clarity and grammatical integrity.

connector usage

Connectors, or conjunctions, link different clauses or phrases in a sentence. They establish relationships such as time, cause, contrast, and addition. In the exercise, the focus is on using a connector that correctly signifies causation. Choosing the right connector is vital:

'Since' can mean 'because,' but it can also describe a period of time starting from a particular moment.

'Because' is more precise in expressing causation, making it the best choice for the sentence in question. Improper usage of connectors can lead to confusion or significantly alter the meaning of a sentence, which is why understanding their roles is crucial.

causation in sentences

Expressing causation in sentences helps to explain why something happens. It involves using connectors that show cause-and-effect relationships. In the provided exercise, the goal was to correctly indicate why the heated discussion arose. 'A heated discussion arose because the possibility of a computer made from DNA and enzymes is such a controversial subject.' Here 'because' clearly connects the cause ('the possibility...') to the effect ('a heated discussion arose'). This clarity in showing why something happened ensures that the sentence is both logical and easy to understand. Being able to correctly convey causation is a critical skill for mastering sentence construction and improving overall communication.
