Correct Answer: Drip irrigation


Solution : The correct option is Drip irrigation.

Drip irrigation is a method of watering plants by using a network of narrow tubes or pipes to deliver water directly to the base of each plant. This targeted approach helps conserve water by minimising evaporation and delivering water precisely where it's needed, promoting efficient and effective plant hydration.

Read the following passage and answer the questions.

All foodstuffs change. Green fruits become ripe and eggs go bad or rotten. It is the enzymes naturally present in each food which bring about the complex chemical changes that lead first to ripening and then to rotting.

How does one control the activity of enzymes, bacteria, yeasts and moulds in food? All of them require air, moisture and a certain temperature, usually somewhere near the body temperature, to be active. Depriving them of one or more of these will suppress them. All microorganisms can be killed by heat sterilisation. This simply means heating the food to high enough temperatures by boiling, deep or shallow frying, roasting, baking and, for milk particularly, pasteurisation. After such sterilisation, if the food is sealed in airtight containers, it can be kept for a long time. A certain water content in food is necessary for microorganisms to be active. Drying in the sun is a simple way of bringing down the moisture level so low that the enzymes and microorganisms cannot flourish.

Some chemicals can suppress undesirable activity. The addition of salt, vinegar, spices and oil or sugar syrup are other ways of preventing foods from going bad. If heating kills, freezing inactivates the enzymes and microorganisms. This is what happens in a refrigerator, in which fruits, vegetables and milk can be kept for fairly long periods. For meat and fish, even colder temperatures, below freezing point, are necessary for preservation. All foods which are kept cold in this way, once taken out and returned to room temperature, are again subject to spoilage and change.

Read the given passage and answer the questions that follow.
'What's your name, boy?' said the gentleman in the high chair. Oliver was frightened at the sight of so many gentlemen, which made him tremble and speak in a very low and hesitating voice.
'Listen to me. You know you're an orphan, I suppose? And that you were brought up by the parish, don't you?'
'Yes, sir,' replied Oliver, weeping bitterly.
'I hope you say your prayers every night,' said another gentleman in a gruff voice, 'and pray for the people who feed you, and take care of you'.
'Yes, sir,' stammered the boy.
'Well! You have come here to be educated, and taught a useful trade,' said the red-faced gentleman in the high chair.

Poor Oliver! He little thought, as he lay sleeping, happily unconscious of things around him, that the board had that very day arrived at a decision which would exercise the most material influence over all his future fortunes.

But they had. They believed the workhouse was a regular place of public entertainment for the poorer classes; a tavern where there was nothing to pay; a public breakfast, dinner, tea, and supper all the year round; a brick and mortar place, where it was all play and no work. 'Oho!' said the board, looking very knowing; 'we are the fellows to set this to rights; we'll stop it all, in no time.'

So, they established the rule, that all poor people should be starved by a gradual process in the house. The water-works were asked to lay on an unlimited supply of water; a corn-factory asked to supply small quantities of oatmeal; and it was decided to issue three meals of thin gruel a day, with an onion twice a week, and half a roll of bread on Sundays.

Question:
How was Oliver feeling?

Option 1: Bored

Option 2: Happy

Option 3: Unconcerned

Option 4: Frightened
