Finding the Antonym of Perfunctory

The question asks us to select the most appropriate antonym for the word "perfunctory" as used in the sentence: "You have made only perfunctory attempts to understand me!"

First, let's understand the meaning of the word "perfunctory".

Understanding the Meaning of Perfunctory

The word perfunctory describes something done quickly, without much interest, care, or effort; it is often done merely as a routine duty. It implies a lack of thoroughness or attention to detail.

In the given sentence, "perfunctory attempts" suggests attempts that were superficial, rushed, or lacked genuine effort and attention towards understanding.

Analyzing the Options

We need to find the word that is the opposite in meaning to perfunctory.

  • Adamant: This means refusing to be persuaded or to change one's mind. This relates to stubbornness or firmness of opinion, not the level of effort or care in doing something. Therefore, it is not an antonym of perfunctory.
  • Careful: This means exercising caution, being thorough, paying close attention to detail, and putting effort into something. Doing something carefully is the opposite of doing it quickly and without much thought or effort (which is perfunctory).
  • Basic: This means forming an essential foundation or starting point; fundamental. It relates to the simplicity or foundational nature of something, not the level of effort or care put into it. Therefore, it is not an antonym of perfunctory.
  • Casual: This means relaxed and unconcerned; informal; done without serious intent or method. This is actually quite similar in meaning to perfunctory, as both imply a lack of seriousness, effort, or thoroughness. Therefore, it is not an antonym; it's closer to a synonym.

Comparing the meanings, "careful" is the most appropriate antonym for "perfunctory" because it signifies the opposite of doing something superficially or without effort; it indicates thoroughness, attention, and effort.

  3. A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
