Ok, so for this question, we have to use our knowledge about graphs.
First things first. The axis titles.
Titles are our best friends because they tell us exactly what the graph is about.
The x axis represents days, and the y axis represents the percentage of transported leaves.
So... our trend has to somehow relate to days and leaves.
That means we can cross off option B...since the graph doesn't say anything about lazy
ants who rely on others to forage leaves...
...and option D, which says that the ants use pheromones
to guide themselves back to the nest on day 3 and 4.
The ants may or may not use pheromones...but we don't care... not for this question, at least.
Right now, all we're concerned with is days and leaves.
Well, both options A and C are about days and leaves.
But...option A says that the ants are the most effective at bringing leaves to the nest
on the first day.
One look at the graph...and we can immediately cross off option A.
The ants were the least effective at carrying leaves on day 1.
They carried... nada. So option A is out.
Which leaves us only with option C.
The trend of the graph is that over time,
the ants become more effective at bringing leaves to the nest.
Guess this would be a leaf of absence.
