Inference

Inference always uses facts to define other facts. For instance, if there is a snake in the house, anyone probably would infer that it will bite someone. 

Thus inference can be true or wrong, reasonable or groundless, valid or invalid.

Conclusion


Mainly two conditions are required in any statement to work as a conclusion. First is that conclusion must be a logically derived statement. Another one is, it does not include inferences from the given statement. For instance, if today is a board exam for Anurag, who lives alone in Delhi and it is heavy rain outside, and he doesn’t drive a vehicle and he knows one of his friends go to school by car. 

So, the conclusion would be that he would contact his friend to take him to the exams.

Example


Himanshu has started giving 8 hours daily to crack the CET exam for admission in a top management school.

Now for ‘Himanshu’, we can conclude.

  • Himanshu is a diligent person.
  • Himanshu is expected to clear the CET exam.
  • Himanshu is a dedicated, strong-minded person.

Now all these three conclusions will be called inferences which were drawn, based on the information provided in the example. Hence inferences can be more than one also.

However, there is always a big confusion between ‘drawing conclusions’ and ‘making inferences’. The below-mentioned table below will clear your doubt about both topics so that fewer chances will be there about the loss of marks in the examination.

Thus, the Inference is an educated prediction while the conclusion more about comes to the next step logically. The common point between the two is both need to find out what is exactly not mentioned.

Inference questions require big imagination skills so that you can catch the meaning of the whole passage and answer questions easily. 

To develop these skills we have divided inference mainly into 3 parts such as:

  1. Deduction Inferences
  2. Speculation Inferences
  3. Inspection Inferences 

A detailed understanding of all these types will surely help you to crack the inference question easily.

Passage 1: Natalie stood at the entrance of the antique store, intrigued by the array of objects displayed before her. Each piece seemed to hold a story, a whisper from the past. She gently picked up an ornate pocket watch, its intricate engravings catching the sunlight. As she turned the watch in her hands, she imagined the hands of time it had witnessed, the places it had traveled, and the people who had cherished it.
Natalie’s attention then shifted to an antique mirror with an elaborately carved wooden frame. She saw her reflection in it, but it was as if the mirror held more than just her image—it reflected the memories of countless others who had gazed into it over the years. The imperfections in the glass seemed to add to its charm, each scratch and mark telling a part of its history.
As she continued her exploration, Natalie stumbled upon a stack of faded letters tied with a silk ribbon. Intrigued, she carefully untied the ribbon and began to read.

 (d)
Dark matter’s gravitational effects are essential in the formation of galaxies and their dynamics. It helps explain the observed rotation curves of galaxies, among other phenomena.

Passage 5: Bonsai is an ancient and intricate horticultural practice that originated in China and was refined in Japan. It involves the cultivation of miniature trees in small containers, creating living works of art. Bonsai artists meticulously shape and train these trees, often over decades, to mimic the appearance of full-grown trees found in nature. The art of bonsai combines principles of horticulture, aesthetics, and patience, resulting in captivating living sculptures.
Q: What is the main goal of shaping and training bonsai trees?
(a) To mimic the appearance of full-grown trees in nature.
(b) To produce fruit-bearing trees in small spaces.
(c) To create genetically modified trees.
