Use 4 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 16 repair kits 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 riverside workshop and check the inventory.

Count the 64 repair kits before visitors arrive. Confirm a clear entrance and an accessible work area at the riverside workshop, then give each of the 4 group leads the same timing sheet.

Supplies: 64 × $2.95 = $188.80. Reserve: $188.80 × 0.10 = $18.88. Planned total: $207.68. This is a planning calculation using the supplied prices.

Remove 16 units, leaving 48. Supplies become $141.60; a 10% reserve adds $14.16, for a total of $155.76.

Join Bicycle Repair Day this Sunday at the riverside workshop. Meet neighbors, learn together, and take part at your own pace. We will share the available repair kits across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Bicycle Repair Day Sunday · riverside workshop Welcome! Ask the desk about available repair kits and today’s small-group activities.

```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: repair kits,64 ```

The row `repair kits,64` should pass. The row `repair kits,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Bicycle Repair Day Location: riverside workshop; day: Sunday. Inventory: 64 repair kits, allocated as 4 groups × 16. 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 16 repair kits 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 repair kits. 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 repair kits before checking the group capacity. Keep the reply specific to the riverside workshop session and offer a clear next step: speak with the welcome desk.
