The nineteenth and early-twentieth centuries saw devastating outbreaks of cholera, typhoid, typhus and influenza in European cities. Physicians such as Jon Snow, from England, and Rudolf Virchow, of Germany, saw the connection between poor living conditions, overcrowding, sanitation and disease. A recognition of this connection led to the replanning and rebuilding of cities to stem the spread and severity of epidemics. link
Which role does 'to infinitive clause'("to stem the spread and severity of epidemics") do grammatically?
- a postmodifier of the noun "replanning and rebuilding"(in this case, the 'to infinitive clause' is included in the noun phrase headed by 'replanning and rebuilding')
- an adverbial clause that expresses 'Purpose'(in this case, 'to infinitive clause' is not included in the noun phrase headed by 'replanning and rebuilding') Which is right?
Distinguishing between these roles always makes me confused because every example has its own context. Thanks in advance:)
