Critical Reading B2

🕵️‍♂️

Evaluating Arguments

ការវាយតម្លៃអំណះអំណាង

To read critically at a B2 level, you must separate strong evidence from weak claims.

ដើម្បីអានប្រកបដោយការត្រិះរិះពិចារណា អ្នកត្រូវចេះបែងចែករវាងភស្តុតាងរឹងមាំ និងការអះអាងដែលខ្សោយ។

Core Vocabulary

វាក្យសព្ទគន្លឹះ

Argument /ˈɑːrɡjəmənt/ អំណះអំណាង (ហេតុផលដែលបញ្ជាក់ពីគំនិតអ្វីមួយ)

Claim / Premise /kleɪm/ / /ˈprɛmɪs/ ការអះអាង (ចំណុចដែលគេលើកឡើងថាពិត)

Evidence /ˈɛvɪdəns/ ភស្តុតាង (ទិន្នន័យ ឬការពិតដែលគាំទ្រការអះអាង)

⚖️

Strong vs. Weak

ភាពរឹងមាំ និងភាពខ្សោយនៃអំណះអំណាង

✔️ Valid (Strong)

An argument supported by facts, statistics, or expert studies.

"Smoking causes lung cancer. Studies by the WHO show a 90% correlation."

សមហេតុផល: មានការគាំទ្រដោយការពិត តួលេខ ឬការសិក្សា។

❌ Invalid (Weak / Flawed)

An argument based on feelings, assumptions, or no evidence.

"Smoking isn't that bad. My grandfather smoked and lived to be 90."

មិនសមហេតុផល (មានកំហុសឆ្គង): ផ្អែកលើអារម្មណ៍ ការស្មាន ឬគ្មានភស្តុតាង។

🎯

Fact vs. Opinion

ការពិត ទល់នឹង មតិយោបល់

Objective /əbˈdʒɛktɪv/ សត្យានុម័ត (ផ្អែកលើការពិត មិនលម្អៀង)

Subjective /səbˈdʒɛktɪv/ អត្តនោម័ត (ផ្អែកលើមតិ ឬអារម្មណ៍ផ្ទាល់ខ្លួន)

A strong argument relies on objective evidence, not subjective opinions!

Logical Fallacy 1 ⚠️

Opinion Disguised as Fact

(មតិយោបល់ដែលគេបន្លំធ្វើជាការពិត)

The Claim: "Electric cars are clearly the best option for everyone."

This sounds like a fact, but it is a subjective opinion. What makes it the "best"? There is no evidence here.

Logical Fallacy 2 ⚠️

"Because I Said So" (Missing Evidence)

(ការអះអាងដែលគ្មានភស្តុតាងបញ្ជាក់ទាល់តែសោះ)

The Claim: "You should buy this stock. It's going to go up."

Always ask: Where is the proof? If the text doesn't provide data, statistics, or expert quotes, the argument is weak.

Teacher, does "valid" mean "true"?

Excellent question, Sokna! Not exactly. "Valid" means the argument makes logical sense based on the evidence provided. The evidence itself might be fake! That's why critical readers must check if the argument is valid AND if the evidence is actually true. 🕵️‍♂️

Hi Vannak! Fake news often relies heavily on subjective opinions disguised as facts (Fallacy 1), uses extreme emotional language, and provides ZERO solid evidence or links to actual studies. If an article makes a huge claim but says "people say" instead of showing data, be suspicious! 🚫
