The forces of globalisation have [1] the economic landscape beyond recognition. Nations once capable of [2] their own needs have grown deeply dependent [3] international supply chains for raw materials, technology, and consumer goods. This interdependence, while fostering prosperity, has made economies [4] to disruptions originating in distant markets. The 2008 financial crisis, for instance, originated in the United States before rapidly [5] to economies across Europe and Asia. Policymakers recognised that unilateral responses were wholly inadequate to address crises of such global magnitude. International bodies such as the IMF stepped in to coordinate a multilateral response. Despite these efforts, critics argue that the gains of global trade have not trickled down to the poorest populations, thereby exacerbating the very inequalities that development was meant to resolve.

1. Blank [1]
   • A. altered
   • B. reshaped ✓
   • C. modified
   • D. distorted

   The sentence uses the intensifier 'beyond recognition', demanding a verb that conveys deep, structural transformation rather than a surface change. 'Reshaped' implies a fundamental change of form — the standard academic collocation for forces that have reorganised an entire landscape. 'Altered' and 'modified' suggest incremental change, while 'distorted' carries a negative connotation (misrepresentation) that contradicts the neutral analytical tone of the passage.

2. Blank [2]
   • A. sustaining ✓
   • B. meeting
   • C. satisfying
   • D. fulfilling

   The phrase 'capable of ___2___ their own needs' requires a verb that collocates naturally with 'needs' in the context of economic self-sufficiency. 'Sustaining their own needs' means maintaining an ongoing supply of what is required — the most precise choice for describing a nation's self-reliant capacity. 'Meeting' and 'satisfying' are grammatically possible but both carry an implication of a discrete, short-term act rather than a continuous capacity. 'Fulfilling' is used more for obligations or duties, not economic needs.

3. Blank [3]
   • A. to
   • B. upon
   • C. on ✓
   • D. for

   This blank tests the fixed preposition that follows the adjective 'dependent'. The only correct preposition in standard British and academic English is 'on' — 'dependent on X' is the fixed collocation. 'Dependent upon' is an archaic and overly formal variant; 'dependent to' and 'dependent for' are grammatically incorrect in this construction. The sentence 'grown deeply dependent on international supply chains' is the standard phrasing in economics writing.

4. Blank [4]
   • A. exposed
   • B. prone
   • C. susceptible
   • D. vulnerable ✓

   All four adjectives describe sensitivity to harm, but they differ in their preposition and connotation. 'Vulnerable to' is the fixed preposition phrase for being open to attack or harm — the most widely used in macroeconomic and policy writing (e.g., 'vulnerable economies', 'vulnerable to shocks'). 'Susceptible to' collocates better with disease or emotional influence. 'Prone to' suggests habitual tendency. 'Exposed to' is possible but less formal. The passage's formal register makes 'vulnerable' the standard choice.

5. Blank [5]
   • A. transmitting
   • B. migrating
   • C. diffusing
   • D. spreading ✓

   The sentence describes a financial crisis moving from one region to another — the blank follows 'rapidly' and precedes 'to economies'. 'Spreading to' is the most natural phrasal construction; 'spread' is the standard verb for the geographical expansion of a crisis, disease, or phenomenon to new areas. 'Transmitting' requires an active agent. 'Migrating' is used for people or data. 'Diffusing' implies gradual dispersal rather than rapid movement and does not collocate naturally with 'to economies'.
