Detailed Explanations (All in One Place)
Nominalisation refers to the process of transforming verbs (or sometimes adjectives) into nouns. This structure is extremely common in academic, formal, and professional English because it allows ideas to be packaged as abstract concepts rather than actions. At C1 level, learners must recognise subtle morphological patterns, countability distinctions, and stylistic register implications.
1. collapse
The correct answer is collapse because the sentence requires a noun functioning as the head of the noun phrase after “the sudden.” “Collapsing” is a gerund/participle form and would imply an ongoing action rather than an abstract event. “Collapsed” is a past participle and cannot function as a noun here. At C1 level, learners must recognise that some verbs have identical noun forms without suffix changes. “Collapse” is a zero-derivation nominalisation (conversion).
2. investigation
The correct answer is investigation because the sentence requires a countable abstract noun after “a full.” “Investigate” is a verb and cannot follow an article. “Investigating” would create a gerund clause, which does not fit the determiner + adjective + noun structure. The -tion suffix is highly productive in academic English and signals formal register.
3. withdrawal
The correct answer is withdrawal. The suffix -al frequently forms nouns from verbs (arrive → arrival, approve → approval). “Withdraw” is a verb; “withdrawing” suggests process rather than completed event. “Withdrawal” encapsulates the action as a conceptual entity — typical of formal reporting style.
4. expansion
The correct answer is expansion. The -sion suffix signals abstract process nouns common in academic discourse (revise → revision, extend → extension). “Expand” cannot follow “rapid” directly because an adjective requires a noun head. “Expanding” would imply progressive aspect rather than completed or generalised process.
5. introduction
The correct answer is introduction. The structure “the + noun + of” strongly signals nominalisation. “Introduce” and “introducing” would require restructuring (e.g., “introducing several policies”). Academic English prefers the abstract noun form to foreground the concept rather than the actor.
6. implementation
The correct answer is implementation. The -ment suffix forms process/result nouns (develop → development, govern → government). “Implement” is a verb; “implementing” would form a participle clause. The noun allows the phrase to function as an object of “approved.”
7. rejection
The correct answer is rejection. Again, -tion nominalisation is required after the possessive determiner “his.” Possessive structures nearly always require noun heads. “Reject” cannot grammatically follow “his” without being converted into a noun. “Rejecting” would imply an action in progress rather than a completed evaluative stance.
8. discovery
The correct answer is discovery. The -y suffix in this case forms an abstract noun from a verb (discover → discovery). The possessive “scientist’s” signals that a noun must follow. Gerund forms do not work naturally in this syntactic environment.
9. loss
The correct answer is loss. This is an irregular nominal form (lose → loss). C1 learners must recognise irregular morphological shifts, not only predictable suffix additions. “Lose” is a verb; “losing” suggests an ongoing process, whereas “loss” expresses the abstract financial state.
10. analysis
The correct answer is analysis. This is an irregular nominalisation from “analyse.” The -sis ending originates from Greek morphology and appears frequently in academic English (crisis, thesis, basis). Recognising these patterns is essential for advanced academic vocabulary control.
11. rise
The correct answer is rise. This is another zero-derivation nominalisation. “Rising” indicates progressive aspect; “rose” is a past tense verb. In economic discourse, “rise” functions as a countable or uncountable event noun.
12. confirmation
The correct answer is confirmation. The -ation suffix signals formal institutional language. “Confirm” cannot function as a noun; “confirming” would form a participial structure. The phrase “official confirmation” is a common collocation in formal announcements.
13. construction
The correct answer is construction. Again, -tion nominalisation is required after “the.” “Constructing” would indicate the action rather than the abstract project. Academic writing prefers the noun form to compress information and remove agent focus.
14. installation
The correct answer is installation. The -ation suffix transforms the verb into an event noun referring to process or completed system setup. “Install” and “installing” would require clause restructuring.
15. acceptance
The correct answer is acceptance. The -ance suffix forms abstract nouns indicating states or attitudes (tolerate → tolerance, perform → performance). After a possessive noun (“CEO’s”), a nominal head is grammatically required. This structure increases formality and shifts emphasis from action to conceptual stance.
