9.	Suggest a suitable title.The advantage of early rising is the good start it gives in our day’s work. The early riser has done a large amount of hard work, before other men have got out of bed. In the early morning the mind is fresh and there are few sounds or other distractions, so that work done at that time is generally well done. In many cases the early riser also finds time to take some exercise in the fresh morning air, and this exercise supplies him with a fund of energy that will last until the evening. By beginning so early, he knows that he has plenty of time to do throughly all the work he can be expected to do, and is not tempted to hurry over any part of it. All his work being finished in time, he has a long interval of rest in the evening before the timely hour when he goes to bed. He goes to sleep several hours before midnight, at the time when sleep is most refreshing and after a sound night’s rest, rises early next morning in good health and spirit for the labours of a new day.

17.	Students observe fashion shows and try to imitate models. This kind of imitation may be called1. Primary simulation2. Secondary simulation3. Social learning4. Generalisation
Answer» Correct Answer - Option 3 : Social learning Keywords: Simulation: A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models, the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist. Social learning: Social learning is defined as learning through the observation of other people's behaviors. It is a process of social change in which people learn from each other in ways that can benefit wider social-ecological systems. Generalization: Generalization, in psychology, is the tendency to respond in the same way to different but similar stimuli. For example, a dog conditioned to salivate to a tone of a particular pitch and loudness will also salivate with considerable regularity in response to tones of higher and lower pitch. Conclusion: Simulation, social learning, and generalization are similar concepts, in which imitation is done in different situations. In the simulation, imitation of real-world activity is done by the use of some models, in social learning imitation of behavior is done by observing others, and in generalization, the response is given in the same way to different but similar stimuli. Here, the child is learning by observing the models in the fashion show, which is a kind of social learning. Hence, option (3) is correct.

32.	There are two primary methods of drilling cable tool and ________(a) Rotary(b) Rotatory(c) Penetrating(d) Insertion
Answer» The correct choice is (a) Rotary The explanation: Rotary drilled wells are constructed using a drill bit on the end of a rotating drillstem. Drilling fluid or air is circulated down through the drillstem in the hole and back to the surface to remove cuttings. Rotary drilling rigs operate quickly and can reach depths of over 300 m (1000 ft.), with casing diameters of 10-45 cm (4-18 in.). Cable tool drilled wells are constructed by lifting and dropping a heavy drill bit in the bore hole. The resulting loose material, mixed with water, is removed using a bailer or sand pump. This method, also called percussion drilling, reaches depths up to 300 m (1000 ft.). Well diameters can range from 10-45 cm (4-18 in.). The drilling rate is typically much slower than for a rotary rig, but when aquifers are low yielding, they may be more easily identified using this method.

Discussion

38.	Which tender allows anyone to submit a tender to supply the goods or services that are required?(a) Framework tendering(b) Selective tendering(c) Open tendering(d) Close tendering
Answer» The correct choice is (c) Open tendering The best I can explain: On larger projects, there may then be a pre-qualification process that produces a short-list of suitable suppliers who will be invited to prepare tenders. This sort of pre-qualification process is not the same as selective tendering. Open tendering has been criticised for attracting tenders / expressions of interest from large numbers of suppliers, some of whom may be entirely unsuitable for the contract and as a result it can waste a great deal of time, effort and money. However, open tendering offers the greatest competition and has the advantage of allowing new or emerging suppliers to try to secure work.

39.	Designated point on a road where road marking or other means helps pedestrians cross safely is called?(a) Zebra crossing(b) Pedestrian crossing(c) Footpath(d) Subway
Answer» The correct option is (b) Pedestrian crossing The best I can explain: A pedestrian crossing or crosswalk is a place designated for pedestrians to cross a road. Crosswalks are designed to keep pedestrians together where they can be seen by motorists, and where they can cross most safely across the flow of vehicular traffic. Marked pedestrian crossings are often found at intersections, but may also be at other points on busy roads that would otherwise be too unsafe to cross without assistance due to vehicle numbers, speed or road widths. They are also commonly installed where large numbers of pedestrians are attempting to cross (such as in shopping areas) or where vulnerable road users (such as school children) regularly cross.

Answer» Correct Answer - Option 4 : \(4\frac{{11}}{{12}}\) Given: Initial Time = 10 hr 20 min. a.m Final Time = 3 hr 15 min. p.m Concept used: In the 24 hours clock, 1 p.m is written as 13 hours and so on 1 hour = 60 minutes Calculation: 3 hr 15 min p.m = (12 + 3) hr 15 min = 14 hr (1 hr + 15 min) = 14 hr 75 min Now, Interval = 14 hr 75 min - 10 hr 20 min = 4 hr 55 min = \(4\frac{{11}}{{12}}\) hours ∴ The time interval is \(4\frac{{11}}{{12}}\) hours

What is the time interval from 10 hr. 20 min. a.m. to 3 hr. 15 min. p.m in hour unit?1. \(1\frac{{11}}{{12}}\)2. \(2\frac{{11}}{{12}}\)3. \(3\frac{{5}}{{12}}\)4. \(4\frac{{11}}{{12}}\)

Answer» Correct Answer - Option 4 : \(4\frac{{11}}{{12}}\)

Given:

Initial Time = 10 hr 20 min. a.m

Final Time = 3 hr 15 min. p.m

Concept used:

In the 24 hours clock, 1 p.m is written as 13 hours and so on

1 hour = 60 minutes

Calculation:

3 hr 15 min p.m = (12 + 3) hr 15 min = 14 hr (1 hr + 15 min) = 14 hr 75 min

Now, Interval = 14 hr 75 min - 10 hr 20 min = 4 hr 55 min = \(4\frac{{11}}{{12}}\) hours

∴ The time interval is \(4\frac{{11}}{{12}}\) hours

Answer» Correct Answer - Option 2 : 40

Given:

The Tin jar contains 11.5 litres of mustard oil.

2.5 litre of oil used for the house.

The capacity of the plastic jar is 225 ml.
