3. Reading: read the text and fill the gaps with the words below.
shares / loss / sale / deposit / CEO / consultant / fired / location
franchise / expenses / investing/heir/deal/ chain / profit
A few years ago my best friend came into some money. If you don't know
what that means, I'll explain: Basically, his childless aunt died and as the sole (1)
lib. he inherited her property and savings. People told him to buy cars and
expensive clothes, but a financial (2) ... advised him to be careful: 'A fool and his
money are soon parted' we say in English.
My friend took notice of what I was saying and started weighing up different
options. He thought about (3) ... money in different companies by buying (4)...,
or just putting the money in the bank in a savings account.
Eventually he decided to set up his own business. He went to a trade fair and made
a (5) ... with a fast food (0) He spent a lot of money furnishing the premises,
but when it opened it didn't take off the way he had been promised.
I think there were a quite a few reasons for this: Maybe he didn't work out

already put down a (8) ..., and he had too much money tied up in the project to
back out.
Anyway, to cut a long story short, the business went under after a couple of
years. After a few months Mark cut back on the (9) ..., but he was still making a
(10) .... Eventually, he just gave up: He (11) ... the staff and put the premises up
for (12) .... He would have gone bankrupt if he hadn't reacted that way.
The franchise has since been taken over by another (13) .... It just wasn't making a
(14) ... and its (15) ... didn't have much idea about the food industry. Mark didn't
seem so bothered. In fact, I think he was relieved that he didn't have to worry
anymore. He hasn't run out of money yet, anyway!
