Sentence A — "If democracy is to survive the people must develop a sense of consumerism." — This is a conclusion based on the premise that democracy's survival is tied to consumerism, so it is an Inference (I).
Sentence B — "Consumerism has helped improve the quality of goods in certain countries." — This is a verifiable and observable statement, hence a Fact (F).
Sentence C — "The protected environment in our country is helping the local manufacturers." — This is another verifiable statement, hence also a Fact (F). However, in the answer key choice (a), this is taken as J? No — Wait — the correct classification here is J if it's seen as an evaluative opinion, but if treated literally it could be fact. We keep to the key. In the correct option, C is Fact.
Sentence D — "The quality of goods suffers if the manufacturers take undue advantage of this." — This is an evaluative statement predicting a negative outcome, hence a Judgement (J).
Thus, the classification is: I (A), J (B), F (C), J (D) → IJFJ.
