a) Edison was born on February 11, 1847. (To give someone’s place or date of birth, we use the simple past ‘was/were born’.)
b) When he was a child he enjoyed reading. (The past continuous tense is used to talk about an activity that was going on at a point of time in the past. To say that somebody did or enjoyed something, we use the simple past tense.)
c) He read many science and chemistry books. (Here the reference is to the past, so we need a past tense.)
d) Edison sold newspapers and candy when he was twelve years old.
e) When he was 13 or 14, he lost the faculty of hearing.
f) his deafness helped him to be a better scientist (The continuous tenses are only used to talk about ongoing activities.)
g) As he was deaf, he did not have to listen to others.
h) He enjoyed being alone.
i) He enjoyed not hearing the noises of his environment. (Enjoy is one of those verbs that cannot be followed by a to-infinitive.)
j) This allowed him to think clearly without distractions. (Clear is an adjective. We need an adverb to modify the verb think.)
