Question 1

A. Match the sample number and date range from the Wednesday activity with the structure and event with the structure and event

Structure Number	Event	Sample Number	Date Range
Structure 34	Construction

Structure 10

B. Using the timeline on slide 3 and the table from part A, answer the following questions

• Structure ____ was built first.

• Structure ____ was built around the same time that Str. 34 was destroyed.

• Structure ___ and Structure __ were probably used at the same time, but Structure ___ was built just a bit later and occupied a bit longer.

• Structure ____ is built around the same time that Str. ___ was destroyed.

• Are there gaps in the timeline or do the events happen close together? Explain your reasoning

Question 2

A. Which structure or structures appear to have a dramatically different layout and construction than the others at the site? Explain your reasoning.

B. Revisit slides 4 and 5. Based on the chronology you created and the changes you identified in house layout and construction, is change at the Tilcajete sites gradual, sudden, or something entirely different? Explain your reasoning.
