(SOLO 2- Uni-structural)Write an abstract of the article below in Results (around 3-4 sentences): RESULTS AND DISCUSSION For the duplicate sets of reactors in experiments A and B, reactors inoculated with Pond 1 started gas formationsooner and peaked earlier than the Pond 2 and Horse Dung reactors. For both sets of reactors, the reactor seeded with pond bottom soil obtained from Pond 1 had the highest methane generation rate, as well as the largest cumulative volume of methane, followed by Pond 2 and finally the reactor seeded with Horse Dung, as shown in Figure 1(A) and (b) below. The possible reason is that Pond 1 is an older pond compared to Pond 2, and the bottom soil obtained from the Pond 1 may have more stable organic matter accumulated as well as higher nutrient concentrations, leading…
