The four sentences (labelled 1, 2, 3, 4) 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. While you might think that you see or are aware of all the changes that happen in your immediate environment, there is simply too much information for your brain to fully process everything. 2. Psychologists use the term ‘change blindness’ to describe this tendency of people to be blind to changes though they are in the immediate environment. 3. It cannot be aware of every single thing that happens in the world around you. 4. Sometimes big shifts happen in front of your eyes and you are not at all aware of these changes.

Correct answer: 1342
Let's build the paragraph link by link.
Find the opener. Sentence 1 is the natural opener because it introduces the general idea without pointing back to anything already mentioned: you may think you notice every change around you, but there is simply too much information for your brain to process fully.
1 → 3: Sentence 3 continues directly from sentence 1. The pronoun 'It' in 'It cannot be aware of every single thing...' clearly refers to 'your brain' just mentioned in sentence 1. So 3 extends the same idea.
3 → 4: Sentence 4 then gives the concrete result of the brain's limitation: because the brain cannot track everything, even big shifts can happen right in front of you and go unnoticed.
4 → 2: Sentence 2 closes the chain by naming the phenomenon. 'this tendency' refers to the unawareness of changes just described in sentence 4, and psychologists call it 'change blindness.'
Read in order: you think you see everything → the brain cannot process every single thing → so big changes may go unnoticed → psychologists call this tendency 'change blindness.'
