I appreciate your request, but I need to clarify the situation with this passage. The input you've provided consists of: - Figures (two graphs showing field data over years) - A chemical equation (2Fe + 3H₂O → Fe₃O₄ + 3H₂) - A data table (Table 1 showing g Fe₃O₄ produced across different solutions and days) - Another figure (a graph showing pH vs. day) This appears to be a science passage with diagrams, tables, and data—not a traditional ACT English passage with underlined text phrases embedded in prose. The questions reference these visual elements and data directly. **The problem:** The instructions I follow are designed for ACT English passages, which have prose text with specific underlined phrases marked by question numbers. This passage has no underlined text to mark up—it's entirely composed of diagrams, equations, and tables. **What I can do:** If you have an actual ACT English passage (with sentences and underlined phrases marked by numbers), I can render it in HTML with the proper `...N` formatting. Could you provide an ACT English passage instead, or clarify if this is meant to be a different type of content?

Two ways to measure the quality of soil are bulk density and the soil organic matter test, SOM (a measure of the active organic content). High quality soil provides structure to plants and moves water and nutrients, so plants grow in larger quantities, leading to higher crop yields at harvest.

Bulk density is measured as the dry weight of a sample of soil divided by the volume of the sample. A bulk density measure above 1.33 g/cm3 negatively affects soil quality. Figure 1 shows the bulk density levels for 5 different years at Fields A and B.

Figure 1

Table 1 shows how soil quality varies with SOM. Table 2 shows the average SOM at the end of each of the 5 years.

Figure 2 shows the total crop yield at each field at the end of the 5 years.

1. Which set of data best supports the claim that Field A has lower soil quality than Field B?

2. If 8 tons or fewer in crop yields were considered a failed harvest, in which year and in which field would there have been a failed harvest?

3. Suppose a new crop rotation for Field B included legumes and other deep-rooted and high-residue crops. The SOM of this field will most likely change in which of the following ways? The SOM will:

4. Based on Figures 1 and 2, consider the average bulk density and the average crop yields for Fields A and B over the study period. Which site had the lower average crop yield, and which site had the higher average bulk density?

Lower crop yield Higher bulk density

5. As soil quality improves, the number of earthworms increases. Students hypothesized that more earthworms would be found in Field B. Are the data presented in

Table 2 consistent with this hypothesis?

Ferric oxide (Fe2O3) is more commonly known as rust. This is produced in a reaction between iron, a common metal, and water, H2O.

Table 1 shows the amount of Fe2O3 produced over time from 15 g Fe submerged in different liquids: 100 mL distilled water, a salt solution made from dissolving 20 g of salt in 100 mL of distilled water, and a sugar solution made from dissolving 20 g of sugar in 100 mL of distilled water.

The distilled water trial was repeated four times, but for each trial, a total volume of 100 mL of water was buffered to different pH levels.

6. Based on

Table 1, if the amount of Fe2O3 produced on Day 9 had been measured for the salt solution, it would most likely have been:

7. In the experiments shown in

Table 1 and

Figure 1, by measuring the rate at which Fe2O3 was formed every day, the experimenters could also measure the rate at which:

8. Consider the amount of Fe2O3 produced by the salt solution on Day 2. Based on

Table 1 and

Figure 1, the water buffered to pH = 10.0 produced approximately the same amount of Fe2O3 on which of the following days?

9. According to

Table 1, what was the amount of Fe2O3 produced by the sugar solution from the time the amount was measured on Day 6 until the time the amount was measured on Day 8?

10. Based on

Table 1, which graph best shows how the amount of Fe2O3 produced by the sugar solution changes over time?
