<span>The environmental problem affecting Tuvalu is (B) Climate Change. Its effects can be seen on the change of sea level. Sea level rise, is one of the consequences that made a major threat for Tuvalu. This consequence brought by climate change has a big impact on the islands.</span>
Use this:
pH = 7 => neutral
pH > 7 => basic (alkaline)
pH < 7 => acidic
So, a pH of 7.6 means the soil is alkaline.
Now, to reduce the impact you should lower the pH.
Sulfur forms acid (H2S or H2SO4) which will lower the pH.
So, adding sulfur will result in the (at least partial) neutralization of the pH and so reduce the impact on plant growth.
Answers: 1) alkaline, 2) sulfur.
