Question

Write two causes for development this defect

Answer 1

"[The] methods of development aren't empty jugs to pour full of any old, dull words. Neither are they straitjackets woven by fiendish English teachers to pin your writing arm to your side and keep you from expressing yourself naturally. The methods are tools for achieving your purpose in writing, whatever that purpose may be. They can help you discover what you know, what you need to know, how to think critically about your subject, and how to shape your writing."
(X.J. Kennedy and Dorothy M. Kennedy, The Bedford Reader, 7th ed. Bedford/St. Martin's, 2000)
