Two neighbouring fields get the same low rainfall. One is sown with paddy and the other with jowar. Which outcome is most likely?
ABoth crops fail, because no cereal grows with low rainfall
BThe jowar crop survives better because it needs less water
CBoth crops do equally well, because rainfall does not matter
DThe paddy crop survives better because it needs less water
Show answer and explanation
Correct answer: B - The jowar crop survives better because it needs less water
Jowar is a millet suited to dry conditions, while paddy needs plenty of standing water, so jowar copes far better with low rainfall. The reversed choice swaps the water needs of the two crops. Millets are cereals that do grow with low rainfall, and rainfall clearly decides which crop survives.
Q2

A doctor advises a patient to cut down on fried snacks but warns against removing fat from the diet altogether. Which reason explains this advice best?
AThe body can make all the fat it needs out of water
BFat is needed by children only and never by adults
CThe body needs some fat, but too much fat brings health problems
DFried foods contain no fat at all
Show answer and explanation
Correct answer: C - The body needs some fat, but too much fat brings health problems
Fat is a necessary part of a balanced diet and acts as the body's energy store, yet eating far more than is needed leads to obesity and other problems. Adults need fat just as children do, and fried snacks are high in fat rather than free of it. The body cannot build fat out of water.
Q3

Read these statements about reading a food test. (i) A result is best read by comparing it with the control. (ii) One drop of iodine solution on a large dry lump is enough to test the whole lump. Which is correct?
AOnly statement (ii)
BOnly statement (i)
CNeither statement
DBoth statements
Show answer and explanation
Correct answer: B - Only statement (i)
Results are read against the control, which shows what no reaction looks like, so the first statement is correct. A large dry lump must be crushed into a paste so that the solution can reach all of it, so the second statement is wrong. With the second statement false, the choices naming both statements and naming neither are wrong.
Q4
easy
Apples brought from an orchard $1500\ \text{km}$ away are compared with apples from an orchard $20\ \text{km}$ away. Which statement is correct?
AThe apples from the nearby orchard have more food miles
BFood miles depend only on the price of the apples
CBoth lots of apples have the same food miles
DThe apples from the distant orchard have more food miles
Show answer and explanation
Correct answer: D - The apples from the distant orchard have more food miles
Food miles count the distance travelled, so apples carried $1500\ \text{km}$ have far more food miles than apples carried $20\ \text{km}$. Saying the nearer apples have more reverses the idea completely. The two distances are clearly different, and price is not what food miles measure.
Q5
hard
Two thalis hold the same amount of chapati and rice. The first also has dal, curd and a green vegetable, while the second has extra rice and a sweet. Which statement is correct?
ANeither thali can be balanced without a fried item
BThe second thali is more balanced because it holds more food
CThe first thali is more balanced because it adds protein and protective foods
DBoth thalis are equally balanced because both are filling
Show answer and explanation
Correct answer: C - The first thali is more balanced because it adds protein and protective foods
The first thali adds protein from dal and curd along with vitamins, minerals and roughage from the vegetable, so it covers far more components. The second thali only adds more carbohydrate and sugar. A bigger or more filling plate is not the same as a balanced one, and no diet needs a fried item to be balanced.
Q6
medium
A hostel cook plans lunch for students who have come from many different regions. Which is the most sensible reason for offering more than one kind of dish?
AFood from one region carries no nutrients at all
BStudents from different regions are used to different foods
COnly one dish can be cooked at a time in any kitchen
DStudents in a hostel dislike all cooked food
Show answer and explanation
Correct answer: B - Students from different regions are used to different foods
Food habits differ from region to region, so a choice of dishes suits more students. A kitchen can prepare several dishes together, and every region's food supplies nutrients. Hostel students do eat cooked food, so the last reason makes no sense.
