• For "Hundreds of millions of people have gained access to modern sanitation": Due to global efforts in improving sanitation infrastructure, hundreds of millions of people have indeed gained access to modern sanitation. This statement is true.
• For "The number of people facing food insecurity has increased": Factors like climate change, water scarcity (affecting agriculture), and conflicts have led to an increase in the number of people facing food insecurity. This statement is true.
• For "Some waterborne infectious diseases have declined dramatically": With better water treatment, sanitation, and public health measures, diseases like cholera (in some regions) have declined dramatically. This statement is true.
