Question:

Each of the questions below consists of a set of labelled sentences. These sentences, when properly sequenced, form a coherent paragraph. Choose the most logical order of sentences from the options.

To avoid this, the QWERTY layout put the keys most likely to be hit in rapid succession on opposite sides. This made the keyboard slow, the story goes, but that was the idea.
A different layout, which had been patented by August Dvorak in 1936, was shown to be much faster.
The QWERTY design (patented by Christopher Sholes in 1868 and sold to Remington in 1873) aimed to solve a mechanical problem of early typewriters.
Yet the Dvorak layout has never been widely adopted, even though (with electric typewriters and then PCs) the anti-jamming rationale for QWERTY has been defunct for years.
When certain combinations of keys were struck quickly, the type bars often jammed.

Explanation:

Statement C begins the paragraph as it introduces the concept of the ‘QUERTY’ design.
E explains the mechanical problem spoken of in C and hence statement E continues immediately after statement C.
Statement A mentions how this problem was solved with the layout.
Statement B describes an alternate layout designed in 1936 and statement D gives the reason why it- the alternate layout- was not adopted. Thus, the logical sequence is CEABD.

Hence, the correct answer is option 2.
