Command of Evidence
Find textual evidence to support answers
Command of Evidence (SAT Reading)
What Are Evidence Questions?
Two-part question format:
- First question: Answer about passage (main idea, inference, etc.)
- Second question: "Which choice provides the best evidence for the answer to the previous question?"
The Strategy
Work BACKWARDS!
Don't answer Question 1 first!
Better approach:
- Read Question 1 (but don't answer yet)
- Look at Evidence Question 2 - read all 4 line citations
- Find which lines best answer Question 1
- That becomes your answer to Question 1
- Then select those lines for Question 2
Why? The evidence choices LIMIT your options for Question 1!
Types of Evidence Questions
Type 1: Direct Support
Answer is directly stated in cited lines
Question 1: "What was the main finding?" Evidence: Lines that explicitly state the finding
Look for: Clear, direct statement
Type 2: Inference Support
Lines provide information to make inference
Question 1: "What can be inferred about...?" Evidence: Lines that contain clues for the inference
Look for: Information that logically leads to conclusion
Type 3: Support for Opinion/Claim
Lines back up author's perspective
Question 1: "The author suggests that...?" Evidence: Lines showing author's viewpoint
Look for: Author's commentary, not just facts
How to Evaluate Evidence
Good Evidence:
✓ Directly relates to the question ✓ Clearly supports the answer ✓ Specific (not vague) ✓ Complete (not missing key info)
Bad Evidence:
✗ Off-topic (about something else) ✗ Weak connection to answer ✗ Too general (doesn't prove the point) ✗ Incomplete (only partial support)
The Paired Questions Strategy
Step-by-Step:
1. Read Question 1 carefully
- Understand what it's asking
- Don't answer yet!
2. Go to Question 2 (Evidence)
- Read all four line references
- Understand what each one says
3. Eliminate weak evidence
- Cross out irrelevant lines
- Cross out vague/incomplete support
4. Match evidence to Q1 answers
- Which evidence supports which answer?
- Usually 1-to-1 pairing
5. Choose best evidence
- Select strongest, most direct support
6. Answer Question 1
- Choose answer that matches your evidence
7. Answer Question 2
- Select the evidence you identified
Common Traps
Trap 1: Mentions Same Topic ≠ Evidence
Just because lines mention the topic doesn't mean they answer the question!
Example:
- Question: "What caused the decline?"
- Bad evidence: "The decline was significant." (mentions decline but no cause!)
- Good evidence: "Pollution led to the decline." (states cause!)
Trap 2: Partial Evidence
Lines that only partially support the answer
Look for: Complete, full support
Trap 3: True But Irrelevant
Statement is true but doesn't answer THIS question
Always check: Does this DIRECTLY answer what's asked?
Trap 4: Too General
Vague statements that could mean anything
Better: Specific, concrete evidence
What Makes Strong Evidence?
Specificity
Concrete details > vague statements
Weak: "It was important." Strong: "This discovery revolutionized medicine."
Directness
Directly states or clearly implies the answer
Weak: "Many factors were involved." Strong: "Temperature was the primary factor."
Completeness
Contains all parts needed to support answer
Incomplete: "The study found effects." Complete: "The study found significant positive effects on learning."
Relevance
Directly relates to question asked
Irrelevant: Interesting but off-topic Relevant: On-point for this specific question
SAT Evidence Question Patterns
Pattern 1: Cause and Effect
Q1: What caused X? Evidence: Must state the cause
Pattern 2: Main Idea
Q1: What is the main point? Evidence: Lines expressing central idea (usually has opinion/claim)
Pattern 3: Author's Attitude
Q1: How does author feel? Evidence: Lines with evaluative language (positive/negative words)
Pattern 4: Support for Claim
Q1: What supports the claim? Evidence: Facts, data, examples backing up the claim
Pattern 5: Definition/Explanation
Q1: What does author mean by X? Evidence: Lines that define or explain X
How to Practice
Read Each Evidence Choice
Don't just skim - actually read the lines!
Ask: "Does This Answer the Question?"
Be specific - WHICH part answers WHICH part of question?
Look for Key Words
Words that directly relate to question
Test Each Pairing
Evidence A with Answer 1, Evidence B with Answer 2, etc.
Eliminate
Cross out clearly wrong evidence first
Time-Saving Strategies
Don't Read All Four Citations Fully
Skim first, then read closely only promising ones
Start with Extreme Answers
Very specific or very general - often easier to eliminate
Look for Transition Words
"However," "Therefore," "Because" - signal important points
Check Line Numbers
Are they from different parts of passage? Might indicate different topics
SAT Tips
- Work BACKWARDS - start with evidence question
- Read all 4 evidence choices before answering Q1
- Direct support beats partial support
- Specific beats vague
- On-topic is essential - interesting ≠ relevant
- Match evidence to answer choices for Q1
- Eliminate weak evidence first (off-topic, incomplete)
- "Best evidence" = most direct, complete, relevant
- Don't just match keywords - need actual support
- Complete thought needed, not fragment
- 1-to-1 pairing usually exists (Evidence A → Answer 1)
- Trust the text - answer must be supported by actual lines
📚 Practice Problems
1Problem 1easy
❓ Question:
Passage excerpt: (Lines 10-12) "The experiment was conducted over six months." (Lines 22-24) "The results showed a 40% improvement in test scores." (Lines 35-37) "Researchers attributed the improvement to the new teaching method." (Lines 48-50) "Future studies will explore other factors."
Question 1: What did researchers conclude caused the improvement? Question 2: Which lines provide the best evidence?
A) Lines 10-12 B) Lines 22-24 C) Lines 35-37 D) Lines 48-50
💡 Show Solution
Solution:
Question asked: What caused the improvement?
Evaluate each evidence choice:
A) Lines 10-12: "six months" → just timeline, no cause ✗
B) Lines 22-24: "40% improvement" → states result, not cause ✗
C) Lines 35-37: "attributed improvement to new teaching method" → DIRECTLY states cause! ✓
D) Lines 48-50: "future studies" → not about current conclusion ✗
Answer to Q1: New teaching method caused improvement Answer to Q2: C) Lines 35-37
SAT Tip: Look for words like "attributed to," "caused by," "due to" - they signal cause!
2Problem 2medium
❓ Question:
Question 1: The author suggests that social media has had what effect on communication?
Evidence choices: A) "Social media platforms have millions of users worldwide." B) "People now communicate more frequently but with less depth than before." C) "The first social network was created in the 1990s." D) "Privacy concerns have increased in recent years."
Which choice provides the best evidence?
💡 Show Solution
Solution:
Question: Effect of social media on communication
Evaluate evidence:
A) "millions of users"
- About popularity, not effect on communication ✗
B) "more frequently but with less depth"
- Directly describes HOW communication changed ✓
- Specific effect: frequency up, depth down
C) "created in 1990s"
- Historical fact, not effect ✗
D) "Privacy concerns increased"
- About privacy, not communication quality ✗
Answer: B
Why B is best:
- Directly answers "what effect"
- Specific about how communication changed
- On-topic (communication, not just general social media)
SAT Tip: Match the evidence to the SPECIFIC question - "effect on communication" needs evidence about communication changing!
3Problem 3hard
❓ Question:
Question 1: The passage suggests that the scientist's discovery was significant because it:
A) Was unexpected
B) Led to practical applications
C) Challenged existing theories
D) Won awards
Evidence choices: A) "The finding surprised the research community." B) "This breakthrough enabled development of new medical treatments." C) "The discovery contradicted prevailing scientific assumptions." D) "She received international recognition for her work."
Which pairing is correct?
💡 Show Solution
Solution:
Strategy: Match each evidence to corresponding answer
Test pairings:
Answer A (Unexpected) + Evidence A ("surprised") ✓ Match!
Answer B (Practical applications) + Evidence B ("enabled new treatments") ✓ Match!
Answer C (Challenged theories) + Evidence C ("contradicted assumptions") ✓ Match!
Answer D (Awards) + Evidence D ("international recognition") ✓ Match!
All pair correctly - so which is BEST?
Key word in question: "significant because"
Need evidence showing WHY it was important:
- A: Surprising = interesting, but not necessarily significant
- B: New treatments = PRACTICAL IMPACT = significance! ✓
- C: Contradicted theories = important for science, but less direct
- D: Awards = recognition, but that's a result, not why it's significant
Answer: B + Evidence B
Why: Practical applications (medical treatments) show real-world significance, not just academic interest.
SAT Tip: When all pairs match, choose evidence showing IMPACT or CONSEQUENCE, not just description!
