How should I approach this reading question type?

What is the common trap in wrong answers for this category?

The most common trap is 'extreme language' (e.g., 'always', 'never') or 'unsupported inferences' that go beyond what is explicitly stated in the provided text snippet.

Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. The sentence describes a historical discovery that changed medicine in the past. Simple past tense 'transformed' is correct for this completed action. Each sentence in a well-constructed text serves a specific purpose. Consider what role this sentence plays in the argument: does it introduce, support, contrast, or conclude an idea? Understanding why an author includes specific sentences helps you grasp the overall argument. Each sentence should serve a clear purpose: introducing ideas, providing evidence, acknowledging counterarguments, or drawing conclusions. Identify the role to understand the structure.

Key Evidence:

• "The discovery of penicillin"

• "saving millions of lives"

Why others are wrong: A ('To transform' is an infinitive; the sentence needs a finite verb.), C ('Transforming' is a participle; the sentence needs a main verb.), D ('Transforms' is present tense; Fleming made the discovery in 1928.).
