I have some problems when I research o these link to deal with this activity. Can you help me in detail, please?

I choose NewZealand for my activity. You just can find information on these two links:

http://hdr.undp.org/en/composite/HDI

https://databank.worldbank.org/data/download/GDP.pdf

a) Gather the data for the NGDP, RGDP, and GDP Deflator for the following periods: 2008-2009 (Global Financial Crisis), 2018-2019 (Pre-COVID), and 2020, if possible, include data from Q1 of 2021.

b) Investigate on the two components (C, I, G, or NX) that have fluctuated (either

significantly increased or decreased) the most during the specified periods. To

explain your points, you will need to present further information, data, reports, or

news to demonstrate your findings.
