</p>

<ul className="text-xs text-slate-600 space-y-1">

<li>
|

• Provides a NEW example or finding, not a restatement.

<li>
|

• Is directly consistent with the specific mechanism

described.
|

</li>
|

<li>• Makes the claim MORE likely to be true.</li>

<li>
|

• Common patterns: X causes Y → new example of X causing Y;

KEY TECHNIQUE — Flip the Claim

</p>
|

<p className="text-xs text-slate-700">

If the claim is "high metabolic rate = survival advantage," then

CRITICAL WARNING

Looking at the graph first is one of the most costly errors on
|
||||
graph questions. Multiple answer choices will accurately
|
||||
describe the graph — only ONE will match the specific claim in
|
||||
the passage. The graphic alone cannot tell you which one is
|
||||
correct.
