When tackling this passage, pay close attention to the comparison paragraphs . The test often asks you to contrast how traditional pharmaceuticals work versus how these new peptide-based drugs function.
: Located in Paragraph D, line 1 . The text mentions that "Combinatorial chemistry is the branch of synthetic organic chemistry," where "offshoot" serves as a synonym for branch.
: The article concludes with an urgent plea. If rainforests and diverse ecosystems vanish, thousands of potentially life-saving insect chemicals vanish with them. Part 4: IELTS Reading Strategies for this Passage

The text calculates that joining 20 amino acids creates factorial variations ( ), resulting in a number of molecular structures. High-Scoring Strategies for this Passage The text mentions that "Combinatorial chemistry is the
The development of high‑throughput automated screening has demanded from synthetic chemistry large arrays or libraries of compounds to satisfy the investment made in installing these systems. Will combinatorial chemistry be able to meet this demand? Are the syntheses well enough developed to meet this? Peptide and oligonucleotide solid‑phase strategies have been well enough developed over the past 30 years. Will solution methods and other novel chemistries be able to keep apace? Can ‘virtual’ chemistry be used to remedy ‘real’ problems? After all, we are living in a real world.
