A、Planting some trees in the greenhouse. B、Writing a want ad to a local newspaper. C、Putting up a Going Out of Business sign. D、

In February last year, my wife lost her job. Just as suddenly, the owner of the greenhouse where I worked as manager died of a heart attack. His family announced that they were going to close the business because no one in the family wanted to run it. Things looked pretty gloomy. My wife and I read the want ads each day.
    Then one morning, as I was hanging out the "Going Out of Business" sign at the greenhouse, the door opened, and in walked a customer. She was an office manager whose company had just moved into the new office park on the edge of town. She was looking for potted plants to place in the reception areas in the offices. "1 don’t know anything about plants," she said. "I’m sure in a few weeks they’ll all be dead."
    While I was helping her select her purchases, my mind was racing.[24]Perhaps as many as a dozen firms have recently opened offices in the new office park, and there were several hundred more acres with construction underway. That afternoon, I drove out to the office park. By 6 o’clock that evening, I had signed contracts with seven companies to rent plants from me and pay me a fee to maintain them. Within a week, I had worked out an agreement to lease the greenhouse from the owner’s family. Business is now increasing rapidly, and one day,[25]we hope to be the proud owners of the greenhouse.
