the fourth protest to take place here

[james0228]

[ On Lunar New Year’s Eve on Saturday, a small group of Chinese people gathered near the Embassy of China in Seoul for the fourth “white-paper” protest to take place here ] from the korea herald.

What is the meaning and grammatical function of the underlined 'to- infinitive phrase'?

Does it mean 'purpose'?
and Is the preceding 'for- phrase' the subject of infinitive?
Or, Does it just modify the preceding noun 'protest'?

 

[grassy]

It has nothing to do with purpose. It complements "the fourth white-paper protest". It's the same structure as in The children were always last to be served in those days or She was the first woman to have climbed Mount Everest.

 

[Cenzontle]

Counting the protests that have taken place here, this was number 4.
