помогите с заданием на картинке!!

текст по заданию:
Plants have been on the planet for billions of years, ang they lie just about everywhere. In this series, we look at plants that stand out from the rest.
Here I am, in the Indonesian rainforest. Walking through the jungle, I can see many plants and flowers, but none are as impressive as the one I'm looking for. It is quite simply the biggest flower in the world and it was discovered in 1818 by Dr Joseph Arnold and he named it after the explorer. Sir Thomas Stamford Raffles. The plants name is Rafflesi. Now, they are difficult to find and they only last for 2-3 days. I haven't seen one yet, but I know one is near. That's because Rafflesia has a very strong smell. It smells like rotting dead bodies. It smells awful to us, but insects just love it and are attracted to it from kilometres away... And there it is, in all its splendour.
I'm in California now, and I'm in a different kind of forest.
It's the Sequoia National Park and all these trees around me are giant Sequoias. These trees live for thousands of years and reach heights of more than 70 metres. There is one, however, that is the largest of them all. It's called General Sherman, after the famous American soldier and hero, and it is the largest tree in the world. Now, it's not the tallest tree in the world, but it is 84 metres tall and it has got a huge 11 metre-wide trunk. Scientists say the wood in General Sherman would weigh 2100 tonnes, making it the heaviest living thing on the planet. In 2006, a branch fell from the tree. Now, because of General Sherman's size, this was no ordinary branch. It was 2 metres wide and 30 metres long, bigger than most trees.
Scientists say it's natural for these trees to lose branches and the tree is in good health. So, even though it's about 2500 years old, it's still got a long life ahead.
