Identifying Incorrect Usage of the Word 'Control'

The question asks to identify the option where the word 'control' is used incorrectly or inappropriately. Let's analyze the usage of 'control' in each sentence.

Meaning of 'Control'

The word 'control' generally refers to the power to influence or direct behaviour or the course of events, or the ability to manage or regulate something. It implies deliberate management or restraint.

Analysis of Options

• Option 1:

  To keep the population in check, birth control methods need to be implemented.

  In this sentence, 'birth control' refers to methods used to prevent pregnancy, which is a correct and established usage. It signifies regulation and management of population growth.

• Option 2:

  Why are you losing control of yourself over this petty matter?

  Here, 'losing control of yourself' means losing self-restraint or composure. This is a common and appropriate idiomatic use of the word 'control'.

• Option 3:

  We can do nothing except let control take its own course.

  This sentence presents an inappropriate usage of 'control'. The phrase 'let control take its own course' is illogical. 'Control' implies active management or direction. Allowing something to 'take its own course' means letting it happen naturally without intervention. Therefore, 'letting control take its own course' is a contradiction in terms. One might 'let things take their course' or 'let events take their course', but not 'control'.

• Option 4:

  The pilot began panicking when the controls of the aircraft failed to function.

  In this context, 'controls' refers to the devices or mechanisms used by the pilot to operate the aircraft. This is a standard and correct usage, referring to the physical means of control.

Conclusion on Usage

Based on the analysis, the usage of 'control' in Option 3 is incorrect because it creates a nonsensical phrase, contradicting the inherent meaning of the word.
