Option 1 is incorrect because the Poverty Reduction and Growth Facility (PRGF) was not established by the International Development Association (IDA). Instead, the PRGF, now known as the Extended Credit Facility, was established by the International Monetary Fund (IMF) to help low-income countries by providing long-term low-interest loans to support their poverty reduction and economic growth efforts.

Option 2 is correct. The Singapore Regional Training Institute (STI) is one of many institutes that provide training in macroeconomic analysis, policy, and related subjects as part of the IMF Institute`s program. The IMF Institute`s goal is to help countries strengthen their capacity to design and implement effective policies by improving their economic management.

Option 3 is incorrect because both statements are not correct, as described above.

Option 4 is incorrect because not both statements are incorrect - statement 2 is correct.

So, the correct answer is option 2, as Singapore Regional Training Institute (STI) does provide training as a part of the IMF Institute program.
