In following questions, a paragraph has been split into four parts. You have to rearrange these parts to form a coherent paragraph.
A. By reasoning we mean the mental process of drawing an inference from two or more statements or
going from the inference to the statements, which yield that inference.
B. So logical reasoning covers those types of questions, which imply drawing an inference from the problems.
C. Logic means, if we take its original meaning, the science of valid reasoning.
D. Clearly, for understanding arguments and for drawing the inference correctly, it is necessary that we should understand the statements first.
The four sentences (labelled 1, 2,3 and 4) given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.
1. Centuries later formal learning is still mostly based on reading, even with the widespread use of other possible education-affecting technologies such as film, radio, and television.
