1- a situation when you waited for a bus or a train 2- a challenging profession you know about

Sample Answer 2: 
I had an experience of getting stuck in a traffic jam a few days ago. Ordinarily, 
there is less traffic congestion in China. But if unluckily you are stuck in a traffic 
jam, it may take your life near to ordeal. The traffic jam may last for an 
uncertain period of time.
It was Monday and I was on my way to the office. Though I started for the 
office early in the morning, it took over two hours for me to reach there. 
Without any exact reason, there was a traffic congestion on the main street. I 
tried for some shortcuts but it took over 20 minutes to get on the main street 
track. Then I had to wait for the rest of the moments until the jam broken.

I was going to my office. It was an important day for me in the office. A new 
deal was to be signed with a party over some environmental issues. I was 
assigned to prepare the documents on the treaty signing issue. The company I 
worked for mostly deals with the environmental degradation and a group of 
the party from the UN came to China to sign the deal. If the deal is signed, my 
company will be responsible for creating a green environment in workplaces. 
Hence, it was an important matter for the entire office.
I had spent nearly two and half hours on the street. It was an unbearable 
experience. Earlier, I had the similar experience to get stuck in the traffic jams. 
But never had waited for over 15 to 20 minutes. This was a different 
experience with me. Luckily, I took a book with me and started reading the 
book to pass the time. Almost all the vehicles on the street were a standstill. I 
do not know what actually happened on that day. Waiting during a traffic jam 
is never expected by anyone. It kills time unnecessarily and makes the 
moments boring.
The feeling about the traffic jam was unpleasant. It made me late to reach 
office. So, I had to undergo some pressure from my superior authority. The 
deal was set to be signed at 10.00am while I reached office late. And also made 
late to prepare the necessary documents. In fact, all the documents were 
ready and needed a proofing and printing. The processes were simple but 
performing all the tasks took time unnecessarily. I blamed the traffic jam for all 
the undesired events. If there were no traffic jams, I would have reached office 
in time and did everything within due time. But it was my bad luck.
