A rat eating some cake - but if he eats through your electric wires there'll be trouble!

Reading Comprehension 02 - Cause and Effect 2

Many times we come across situations where we wonder why some things happen and why some things donâ€™t. For example, when we switch on a light switch the light comes on and likewise when we switch it off the light goes off. The act of switching on the light switch is the cause of the light coming on. Looked at another way the act of switching on the light switch has the effect of the light coming on. Here, we see a cause and effect relationship.

We do our normal daily routine things without really thinking about the cause and effect relationships but they do exist. More often than not, we are alerted when a cause does not have the desired effect. For instance, in our light switch example we would be surprised if the light does not come on and we would begin to look for reasons why the light did not come on. Again, there will be a cause-effect relationship which will explain why the light did not come on. It could be because there is no power, or the light bulb has burnt out, or there is a fault in the wire that supplies the electric current.

In reading comprehension we begin to look for this cause-effect relationship every time we read a passage. Identifying the cause-effect relationship enhances our understanding of what we read. By reading regularly and understanding the cause-effect relationship we learn to read faster and assimilate what the writer intends to say. Read the passage that follows and take the quiz based on what you read which tests your ability to understand the nuances of the cause-effect relationship.
The other day all the equipment in my house running on electric power shut down when power suddenly went off. Usually, power goes off for some time due to some maintenance work and comes back on within 15-20 minutes. That day, the whole morning was upset and I could not take a bath as the geyser had not worked. The electric toaster was not going to work and so no breakfast.

The first thing I do when there is no power at home is to check if our neighbours have power. If they have power then it means that there is something wrong in my house. Since they had power there must be something wrong in my house only. I went to the main switch board and found that the main MCB was tripping. Tripping happens when there is some problem in the circuit. I had to call an electrician to figure out what the problem was. He checked the circuit and came to the conclusion that there was a short circuit between the main switchboard and the first junction point. He examined the wiring and found the short circuit. The wire had been eaten by rats causing the short circuit. The electrician replaced the faulty wire with a new wire and restored power. One lesson we learn is that proper maintenance goes a long way in preventing mishaps.
1.
What was the cause of the equipment shutting down?
The power suddenly went off.
I switched off the power.
The equipment was faulty.
I had not switched the equipment on.
From the passage it is evident that the effect of the power suddenly going off was to shut down the equipment running on electric power. Thus the cause is the fact that power went off suddenly
2.
What was the effect of the power going off?
That the equipment in my neighbour's house shut down.
That I should call an electrician.
From the passage it is evident that the effect is the fact that I had to call the electrician to let him check what was wrong with our power supply. Remember that one event can cause multiple effects
3.
Why was the geyser not working?
Because there was no water.
Because the power went off suddenly.
Because the geyser was faulty.
Because the geyser was not switched on.
From the passage it is evident that the cause of the geyser not working was the power going off. Remember that the same effect can be felt by different causes
4.
'So no breakfast' - why is this term used in the passage?
Because I was not feeling hungry.
Because the toaster was not going to work.
Because I don't know how to make breakfast.
From the passage it is evident that one cause-effect relationship can affect other outcomes. Here the main cause was the power going off suddenly, due to which the toaster would not work. Since the toaster did not work I could not have breakfast
5.
Which is not an effect of the power shutting off suddenly?
I had to call the electrician.
I could not have breakfast.
I checked if my neighbours had power.
From the passage it is evident that the neighbours had power. The effect of the power going off suddenly was felt only in my house
6.
What was the reason I could not have a bath?
Because the geyser did not work.
Because I had no fresh clothes.
From the passage it is evident that the cause of me not having a bath is the fact that the geyser would not work without power, as the power went off suddenly. One cause-effect relationship can affect other outcomes. Here the main cause was the power going off suddenly due to which the geyser would not work and since the geyser did not work I could not have a bath
7.
Why did the power go off suddenly?
Because the power supply company stopped supply.
Because I switched off the power supply.
Because there was a short circuit.
Because the neighbours stole my power.
From the passage it is evident that the power went off only in my house and the reason was a short circuit. Thus the short circuit was the cause and the effect was power going off in my house
8.
What was the cause of the short circuit?
There was a problem with the geyser.
Rats had eaten into the wire causing a short circuit.
There was a problem with the toaster.
There was a problem with the main power supply.
From the passage it is evident that the wires were eaten by rats and the faulty wires caused the short circuit
9.
What effect did the short circuit have?
It stopped the power supply to my neighbours.
It tripped the main MCB.
From the passage it is evident that the main MCB was tripped. The MCB tripping is the effect and the short circuit is the cause
10.
Power going off for short periods is caused by what?
Maintenance work being carried out.
Faulty equipment.
Power supply company not supplying enough power.
Power supply company forgetting to supply power.
From the passage it is evident that the power supply could go off for short periods when maintenance work is being carried out. The effect of maintenance work being carried out is to interrupt power supply for short periods
