Some years ago, I went to Australia for a meeting with my friend, Chris. We decided to drive across the country to Brisbane after the meeting ended. The drive was going to take four days and most of it was across the desert, so we had to take food, water, and extra gas(汽油) w  1  us.

The first day was a lot of fun as we were excited and laughing at each other’s jokes. By the third day of driving in the seemingly endless desert, we began to get b  2 . We had been quiet for a few hours when Chris found some kangaroos in the distance. We were b  3  excited and decided to get a closer look. Chris speeded up to

Chris s  5  the car and we got out. Behind the car was a larger kangaroo l  6  completely quiet on the ground. Chris went over to the kangaroo and put his baseball cap on its h  7 . He took off his sunglasses and put them on the kangaroo and did the same with his jacket. Then he put his arm a  8  the kangaroo and told me to take a photo of them together. I was still surprised, but I took out my c___9___. While I was ready to take photos, I saw the kangaroo move. It suddenly woke up, looked at Chris, and jumped away into the distance before we could do anything.

I started laughing but Chris looked very serious. He said his wallet and passport were in the jacket. I started laughing even harder. I stopped laughing, h  10 , when he said that our car keys were also in the jacket!

Lebogang owns a shoe retail store in Gaborone. She regularly receives consignments of shoes from Takutaku Wholesalers. In the last six months of 2010, Lebogang had been in negotiations with Takutaku about the price of the shoes supplied to her. Takutaku wished to increase prices by 10% to account for increased costs of materials. Lebogang had been negotiating for only a 5% increment.In February 2011, Takutaku sent a letter to Lebogang stating as follows:‘We have considered your position. We are prepared to offer you the usual shoe consignment at a compromise increment of 7·5% unless we hear otherwise.’In March 2011, Takutaku sent a consignment of shoes to Lebogang. The unit price on each pair of shoes supplied had been increased by 7·5%. Lebogang did not reply to Takutaku.In September 2011, Takutaku sent Lebogang a letter of demand claiming payment for the March 2011 consignment. Lebogang then responded as follows:‘You will be well aware that negotiations between us were inconclusive. Whilst your company advocated a 10% increment, I had maintained that a 5% increase was the maximum that I was prepared to accept. I am not liable to you on the new price.’Takutaku disagrees with the position that Lebogang has taken and wishes to sue Lebogang for the amount due on the consignment of shoes delivered in March 2011.Required:Advise Takutaku.
