Use 4 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 12 guide cards to each group. 00:20–01:05: run the main activity. 01:05–01:20: collect feedback and reusable equipment. 01:20–01:30: clean the museum lobby and check the inventory.

Count the 48 guide cards before visitors arrive. Confirm a clear entrance and an accessible work area at the museum lobby, then give each of the 4 group leads the same timing sheet.

Supplies: 48 × $4.00 = $192.00. Reserve: $192.00 × 0.10 = $19.20. Planned total: $211.20. This is a planning calculation using the supplied prices.

Remove 12 units, leaving 36. Supplies become $144.00; a 10% reserve adds $14.40, for a total of $158.40.

```python import csv def read_inventory(path): rows = [] with open(path, newline="", encoding="utf-8") as handle: reader = csv.DictReader(handle) if reader.fieldnames != ["item", "quantity"]: raise ValueError("Expected item,quantity columns") for line, row in enumerate(reader, 2): name = row["item"].strip() quantity = row["quantity"].strip() if not name or not quantity.isascii() or not quantity.isdecimal(): raise ValueError(f"Invalid inventory row {line}") rows.append((name, int(quantity))) return rows # Example row: guide cards,48 ```

The row `guide cards,48` should pass. The row `guide cards,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Accessible Museum Tour Location: museum lobby; day: Wednesday. Inventory: 48 guide cards, allocated as 4 groups × 12. Before opening: count supplies, set the welcome desk, and confirm group leads. During the event: record shortages and visitor questions. After closing: count returns and write one improvement for the next meeting.

Ask: “Were 12 guide cards per group enough for the activity, and which step created the longest wait?” Record the answer beside the returned inventory count.

You are welcome to check in at the desk when you arrive. A coordinator can explain the current activity and see whether a group has space and spare guide cards. If the activity is already full, we can help you observe or find the next joining point.

Avoid guaranteeing a place or a set of guide cards before checking the group capacity. Keep the reply specific to the museum lobby session and offer a clear next step: speak with the welcome desk.
