A. What is the reading text about?

a. School Introduction
b. Family Introduction
c. Self Introduction

B. Draw a line between what we can know from the reading text as in the example.
And referring the reading text, fill in the blanks.

O. What is her dwelling place? From the reading text, we can get the information about her hometown. It was Busan. So, you should write down 'Busan' in the blank. After that draw a line between 'Dwelling Place' and her picture.

O. What is he specialty? Can we know her specialty from the reading text? No, we can't. So you don't need to draw a line between 'Specialty' and her picture. Mark an X in the blank.

I changed expressions in our language into English. (above)
Would you checked them, and let me know incorrect expressions?
I'd like to use correct and natural expressions. Thank you.

The phrase "the reading text" is quite awkward. You should either write "the text" (if you intend a noun) or "reading the text" (if you intend a verb).

I'd make changes as follows:
-----------------
A. What is the text about?
a. School Introduction
b. Family Introduction
c. Self-introduction

B. Draw a line between what we can know from reading the text as in the example.
And referring to the text, fill in the blanks.

O. What is her dwelling place? From reading the text, we can get the information about her hometown. It was Busan. So you should write 'Busan' in the blank. After that, draw a line between 'Dwelling Place' and her picture.

O. What is her specialty? Can we know her specialty from reading the text? No, we can't. So you don't need to draw a line between 'Specialty' and her picture. Mark an X in the blank.

A. The reading text is about c. Self Introduction.

B. Regarding your expressions, there are a few minor corrections that can be made to make them more accurate and natural:

1. What is her dwelling place? From the reading text, we can find information about her hometown. It is Busan. Therefore, you should write down 'Busan' in the blank. Then draw a line between 'Dwelling Place' and her picture.

2. What is his specialty? Can we determine his specialty from the reading text? No, we cannot. So you don't need to draw a line between 'Specialty' and his picture. Mark an X in the blank.

Overall, you have done a good job in conveying the meaning, but these small tweaks will make the expressions more appropriate.
