Expresses the basis or perspective from which a judgment or inference is made — 'judging from X' or 'from X's point of view.' It commonly follows evidence you observe or a person whose viewpoint you take. The main clause usually contains a guess or evaluation.

外国人 (foreigner) marks whose viewpoint frames the judgment
• Two uses: (1) 'judging from [evidence]', (2) 'from [someone's] standpoint'. • The main clause is typically a conjecture or evaluation. • Interchangeable with から見ると in most contexts.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~からすると/からすれば is tested against.
からすると takes a source/person as the vantage point to infer or evaluate, while からいうと judges strictly in terms of an abstract standard or criterion.
Both mean 'judging from'; からすると leans slightly more toward reasoning/inference, while から見ると emphasizes the visual or observational vantage point. They are largely interchangeable.
