The graphic shows the island of Krakatoa, which disintegrated in 1889, due to the largest volcanic eruption in recorded history. In the century since the eruption, the island has reformed from lava flows. The table above shows the number of species of various plant types that were found on the island over a 30 year period since the island resurfaced above the ocean in the 1950's.
During what survey time did it appear that grasses out-competed weeds for resources?

I don’t have the table/image you mentioned, so I can’t pick a year with certainty. I can tell you how to decide:
- Look at the counts for grasses and for weeds at each survey year.
- The year when grasses appear to out‑compete weeds will be a year where the number of grass species increases while the number of weed species decreases (or when grasses first become more numerous than weeds).
- Compare each year to the previous survey and pick the first year that meets one of those conditions.
If you paste the table or the grasses/weeds counts for 1964, 1974, 1979, 1984, and 1989, I’ll pick the correct letter for you.
