The "buzz" refers to the surge in interest and application of in the agrochemical, biotechnology, and pharmaceutical industries. It is not merely a passing trend but a revolution in the way researchers create molecular libraries to identify potential new drugs. Key Aspects of the Process:
: The passage describes it as a "buzz term," implying it is currently very popular or "in vogue".
Identify the required part of speech (e.g., adjective, idiom) to accurately complete summary sentences.

Plants use hidden ultraviolet patterns—invisible to humans but highly visible to pollinators—to act as landing strips for bees.
Question text: "Below is a list of the regular types of contributors to chemistry reviews. Which three contributors are described by the writer? Write your answer A‑F in the order they occur in the text."
These reviews all have the same format. First, there is the section from research and development director of a major chemical company, a person who has not worked at the bench for years, if not decades. This is filled with business speak; the jargon keeps the shareholder happy and makes them proud to own a bit of something at the forefront of science. Section two is from a director of a venture capital funded synthetic chemistry company located on a green field side, probably in a protacabin, or, perhaps, in a new business park, rent free for the first five years from the local authority of a small town no one has heard of. He discusses the molecular modeling packages that they are using to build 'virtual' libraries containing millions of compounds. The third section is by someone who, in fact, practices combinatorial chemistry and who developed automated system to do the syntheses and to assay the products. The "buzz" refers to the surge in interest
Dr. Elena Marchetti first noticed the buzz during a late-night analysis of honey samples from the abandoned orchards of Chernobyl. It wasn’t an audible sound, but a hum in her data — a strange, repeating electrical spike in the gas chromatograph readings.
Based on common versions of this test, such as those found on Kanan.co and IELTSMaterial , here are the answers for the section:
(The researchers won an international award for their discovery.) Identify the required part of speech (e
Paragraph F – So, why does this buzz matter? Public perception of chemistry has long been tainted by pollution and industrial disasters. These new frontiers – green chemistry, computational design, and single-atom efficiency – promise a cleaner, more precise, and more innovative chemical industry. The buzz, therefore, is not just academic excitement; it is a signal of transformation.
C Explanation: Paragraph C lists “organic chemistry is the chemistry of carbon, biochemistry the chemistry of life and physical chemistry the application of physics”. These are the more widely understood fields before introducing combinatorial chemistry.
The passage describes combinatorial chemistry as a "branch" of synthetic organic chemistry. In this context, "offshoot" is the matching synonym. Answer: 160,000 Location: Paragraph E

After the development of solid-phase peptide synthesis in the 1960s by Merrifield, synthetic peptide chemists were also doing permutation and combination sums. There are 20 naturally occurring amino acids, the building blocks of peptides and proteins, the workhouse molecules of life. How many ways can these be arranged, or chemically bonded, to synthesize novel peptides which might be put to any number of uses in the pharmacy? If we take just one molecule of each of the 20 amino acids and join them together to form a peptide, we find that we can arrange these in 20! or 2.432902008177×10¹⁸ ways. Nature knows no such restraint; it can use multiple copies of each amino acid, and so can synthesize 20²⁰ or 1.048576×10²⁰ twenty amino acid peptides. Proteins contain hundreds of amino acids. The number of possible sequences is truly innumerable!
