HSC ICT Chapter 2 : Comprehension Based Questions & Answers

How to write answers to a comprehension based question?

‘Comprehension’ refers to the ability to understand the meaning of a topic. It can be the ability to understand any information, policy, formula, rule, procedure, process etc.

Perceptual level is the second level of thinking skills. This question is given in ‘b’. Such questions do not directly ask for textbook-like details. So the student has to explain or describe the content in his own way.

Marks of comprehension based question will be 2. Out of which 1 is for knowledge and 1 is for comprehension.

Comprehension based questions should be answered in two paragraphs. Answers to knowledge section in the first paragraph and understanding section in the second paragraph.

Answers to comprehension based questions should be written in a maximum of five sentences as per the instruction of the Ministry of Education. But there is no problem if it is a little more or less.

In this case, irrelevant words, unnecessary information or redundant accusations cannot be made in the answer to the question.
