Example Input: These Twix bars are produced in the Netherlands; they do not taste the same as US-produced Twix, so if you are expecting the US version, you will be disappointed. The expiration date on the lot I purchased was 2 days after the shipment was delivered.
Example Output: 1

Example Input: These cartridges are a great alternative to the OEM at a fraction of the cost. The only downside is you are guessing at what color you are opening unless you find the sticker of what color it is through the yellow bag that they are each individually packaged in. The shipping box is solid and the foam fits great. All 4 are in one box and arrived perfectly.
Example Output: 4

Example Input: The easiest way to spread it was to use a mesh strainer around the room. Be aware that it does create a fair amount of dust when shaken and will cause some irritation to your lungs and eyes. This worked well for ridding our house of fleas as it's 75% carpeted. For a cheap option it wasn't bad.
Example Output:
