Answer and explanation

The 2026 Lee Yu-jin Korean Reading Algorithm Pro series
―Continuous management through in-depth training for each weakness after embodying the methodology by type.

The Lee Yu-jin Korean language curriculum is comprised of the stages of 'embodying methodologies by type' and 'practical training' in line with the changing standards of the civil service Korean language exam.
The "Reading Algorithm Pro" series is a textbook for in-depth training in "embodying type-specific methodologies." It consists of five core areas: structural reading and confirmatory reasoning, which are the foundation of reading comprehension and training areas for intensive reading and speed reading; applied reasoning for processing information according to intent; highly discriminatory logical criticism; and linguistics.


[Structured Reading]
We conduct intensive reading training to broaden the scope of understanding by selecting key information from sentences to paragraphs and from paragraphs to text units.
Learning how to read a passage in summary form by structure will help you read faster.

[Confirmation Inference]
We provide training to accurately judge the options such as matching, understanding, and inference based on the information presented in the fingerprint.
Quick answers by sequentially tackling problems of various sanctions and difficulty levels according to a systematic method
It helps you make decisions.

[Applied Reasoning]
We train you to actively provide answers to various applied reasoning problems (context reasoning, gap reasoning, case reasoning) and then approach the options.
Communication styles (speaking and writing) are also covered here.

[Logical Criticism]
In line with the intention of the sample evaluation of the Ministry of Personnel Innovation, the high school Logic textbook, which is part of the secondary education curriculum, was used as the standard for the scope of study.
Essential logic concepts are taught in a sequential manner, making them easy to understand through examples, and through problem-solving practice by type, enabling students to solve even difficult problems.

[linguistics]
Now, what is needed is not 'memorized grammar' but 'linguistic training that allows you to understand and apply the knowledge in texts' and 'the ability to write official documents necessary for practical skills'.
We arrange the problems in order to help you naturally form an overall schema for 'linguistics (grammar) concepts' and provide practice problems created using materials published by the National Institute of the Korean Language and the Ministry of the Interior and Safety.
