Professor Rodriguez: The kingdom of Xincua experienced significant population loss in the 10th century. The best explanation for this is a drier climate that lasted about 100 years. That period included some less dry decades but also at least four extremely dry decades, as attested by tree-ring and sediment data. During these decades, growing crops became harder, especially since the semiarid Xincua territory needed extensive irrigation even in less dry periods. The resulting population loss and unrest—arising from out-migration, increasing mortality due to poorer nutrition, and a lower birth rate—likely made maintenance of irrigation systems more difficult. Some small dams, for example, deteriorated significantly during the dry period.

Based on the information provided, which one of the following statements concerning the primary cause of population decline in 10th century Xincua, if it were shown to be true, would most strengthen the support for Rodriguez's position, while undermining the support for Ojukwu's position?
| Declining government revenue made it difficult to ensure continued functioning of irrigation systems. | |
| There had been some ongoing migration out of Xincua even up to the end of the 9th century. | |
| Drastic reductions in water supply led to civil strife and mass out-migrations and impaired kings' ability to rule. | |
| Conflict among political factions increased as population declined. | |
| Political instability damaged the society's ability to deal with crises such as a decline in the water supply. |

1. We are asked to check which statements are true or false.
- It provides some support for an assertion made by Rodriguez. Rodriguez states that there was a drought: "that period included some less dry decades but also at least four extremely dry decades." The table shows that most of annual rainfall amounts are less than average and 4 decades had under 260. So, this statement is true.
- It provides some support for an assertion made by Ojukwu. Ojukwu states that there was a lot of instability: "the turmoil is shown by the very short reigns of kings in the 900s, especially in the period 920-959, indicating instability that toppled kings." The table shows that a lot of the reigns were way below average and that it happened especially between 920 to 959. So, this statement is true.
- It provides conclusive proof that an assertion made by Rodriguez is incorrect. The table doesn't show anything to dismiss Rodriguez and as earlier stated, it rather supports their statement. So, this statement is false.
2. The question asks to find whether the two professors would both agree on the statements.
- The largest amount of Xincua's 10th-century population loss occurred after 940. Both professors never pinpointed when in the 10th century did the population loss happen. So, this statement is a no.
- Parts of Xincua's irrigation systems declined during the 10th century. Rodriguez said: "made maintenance of irrigation systems more difficult. Some small dams, for example, deteriorated significantly during the dry period." Ojukwu said: "also, irrigation systems deteriorated; evidence from similar cultures of the time suggests that vandalism against public installations was a form of protest." So, this statement is a yes.
- The general standard of nutrition in Xincua declined during the 10th century. Rodriguez said: "increasing mortality due to poorer nutrition." Ojukwu said: "the political situation ultimately led to out-migration, poorer nutrition, and fewer births, resulting in a declining population." So, this statement is a yes.
3. We need to find a statement that supports Rodriguez but undermines Xincua. Such a statement could state that a drought is the cause behind the turmoil, and thus the drought would be the main cause behind the population loss. The only statement that would work is: "Drastic reductions in water supply led to civil strife and mass out-migrations and impaired kings' ability to rule."

In question 1 third part, why is the answer YES wrong.
"It provides conclusive proof that an assertion made by Rodriguez is incorrect."
As per professor R
"That period included some less dry decades"
but decade 950-959 was not dry at all as per the table.
