A statement is given followed by two inferences I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given inferences, if any, follow from the given statement.
Statement: Literature is a form of ugliness so intolerable that we have to alter it every six months.
Inferences: I. Authors do not understand the public mind very well.
II. The public, by and large, is highly susceptible to novelty.
The statement asserts that people do not condone a particular trend for a long time and want to change it quite often. The first inference cannot be drawn as nothing about the authors’ mind set can be inferred. Thus only inference II follows because the public wants a change and wants something original all the time. Thus, literature is altered every six months to suit the taste of the public.

A mother’s age is thrice that of her daughter’s age. Six years ago, the mother’s age was five times that of the daughter’s age. What was the daughter’s age 6 years ago?
Let the daughter’s age six years ago be ‘y’.
Then mother’s age six years ago = 5 × y
Daughter’s age at present = y + 6
Mothers age at present = (5 × y) + 6
According to the question, mother’s age at present = (5 × y) + 6 = 3 × (y + 6)
Solving, we have:
y = 6
Hence the daughter’s age six years ago was 6 years.
Which of the following interchange of signs would make the given equation correct?

The property of the material to regain its original shape after deformation when the external forces are removed is ________.
Elasticity is the property of a material to regain its original shape after deformation when the external forces are removed. All materials are plastic to some extent but the degree varies, for example, both mild steel and rubber are elastic materials but steel is more elastic than rubber.
Plasticity of a material is its ability to undergo some degree of permanent deformation without rupture or failure. This property is important in forming, shaping, extruding and many other hot and cold working processes.
Durability is defined as the ability of a product to perform its required function over a lengthy period under normal conditions of use without excessive expenditure on maintenance or repair.

The total area under the stress-strain curve of a mild steel specimen tested up to failure under tension is a measure of its:
Strength is defined as the ability of the material to resist, without rupture, external forces causing various types of stresses. Breaking strength is the ability of a material to withstand a pulling or tensile force.
Toughness is defined as the ability of the material to absorb energy before fracture takes place. In other words, toughness is the energy for failure by fracture. Toughness is measured by a quantity called modulus of toughness. Modulus of toughness is the total area under a stress-strain curve in tension test, which also represents the work done to fracture the specimen.
Hardness is defined as the resistance of a material to penetration or permanent deformation. It usually indicates resistance to abrasion, scratching, cutting or shaping.
Stiffness or rigidity is defined as the ability of the material to resist deformation under the action of external load. Modulus of elasticity is the measure of stiffness.

The water utilizable by plants is available in the form of:
Gravitational water: Gravitational water occupies the larger soil pores (macropores) and moves down readily under the force of gravity. Water in excess of the field capacity is termed gravitational water. Gravitational water is of no use to plants because it occupies the larger pores.
Hygroscopic water: The water that held tightly on the surface of the soil colloidal particle is known as hygroscopic water. It is essentially non-liquid and moves primarily in the vapour form. Hygroscopic water held so tenaciously by soil particles that plants cannot absorb it.
Capillary water: Capillary water is held in the capillary pores (micropores). Capillary water is retained on the soil particles by surface forces. It is held so strongly that gravity cannot remove it from the soil particles. The molecules of capillary water are free and mobile and are present in a liquid state. Due to this reason, it evaporates easily at ordinary temperature though it is held firmly by the soil particle; plant roots are able to absorb it.
Lacey’s regime theory is not applicable to a channel in
Lacey said that even a channel showing no silting no scouring may actually not be in the regime. He differentiated three regime conditions,
(i) True regime
(ii) Initial regime and
(iii) Final regime
According to him, a channel which is under ‘initial’ regime is not a channel in a regime, as there is no silting or scouring and hence regime theory is not applicable to such channels. His theory is therefore applicable only to those channels, which are either in true regime or in the final regime.
