Reading comprehension
My father, at
the death of his father,
was six years old,
and he grew up without education,
He moved from Kentucky to Indiana when I was seven.
We reached our new home about the time the state
came into the union. It was a wild area, with many bears and other wild animals
still in the woods.
I grew up there.
There were some so called schools,
but what was required of a teacher never went beyond
“ reading, writing,
and adding. ” If a stranger supposed
to understand Latin
happened to live for a time,
he was looked on as a wizard.
There was simply nothing
to excite a desire for education.
Of course, when I grew up, I did not know much. Still, somehow, I could
read, write,
and add, but that was all. The advance I have now made is upon this
store of education,
which I have picked up under the pressure of necessity.
1 It can be inferred
from the passage that the school in the area________.
A. were of poor quality B. offered many kinds of subjects

2 From the passage

advanced education

of education.
