San Clemente is an Island off the coast of San Diego.
A)
Exclamatory
B)
Affirmative
C)
Imperative
D)
Negative
The sentence 'San Clemente is an Island off the coast of San Diego.' is a simple statement that gives information. Such sentences are called affirmative or declarative sentences. It is not exclamatory because it does not express strong emotion, not imperative because it does not give a command/request, and not negative because it contains no negation like 'not'.
That he is a cheat is a well known fact. (Identify the clause of the underlined words)
A)
noun clause
B)
adverb clause
C)
adjective clause
D)
independent clause
"That he is a cheat" functions as a noun clause because it acts as the subject of the sentence. The whole clause is the thing being stated as a fact. It can be replaced by a noun phrase like "His being a cheat is a well known fact." It is not an adverb clause because it does not show time, reason, condition, etc. It is not an adjective clause because it does not describe a noun in the main clause. It is not an independent clause because it cannot stand alone as a complete sentence.
Andy knocked on the door but nobody answered. (Identify part of speech of 'but')
A)
Adverb
B)
Adjective
C)
Conjunction
'But' joins two clauses: 'Andy knocked on the door' and 'nobody answered.' It is used here as a coordinating conjunction showing contrast. It is not an adverb or adjective in this sentence.
They all said that I would not succeed. (Identify the clause of the underlined words)
A)
noun clause
B)
adverb clause
C)
adjective clause
D)
independent clause
The underlined part is "that I would not succeed." It functions as the object of the reporting verb "said" and answers the question: said what? So it is a noun clause. An adverb clause would show time, reason, condition, etc.; an adjective clause would modify a noun; and an independent clause can stand alone, which this clause cannot.
Tis snatestawesions drive to work because of the traffic jams.
A)
rarely
B)
usually
C)
occasionally
D)
allthe time
The sentence says the person drives to work because of traffic jams, which implies this is the normal or regular habit. 'Usually' best fits this meaning. 'Rarely' and 'occasionally' suggest infrequent action, and 'all the time' is too absolute.
Remuneration
A)
Understanding
B)
Protest
C)
Finality
D)
Compensation
“Remuneration” means payment or reward for work done, i.e., compensation or salary. Among the options, “Compensation” is the closest synonym. The other options do not match the meaning: understanding = comprehension, protest = objection, and finality = conclusion.
Drive to the roundabout and then turn left:
A)
Exclamatory
B)
Imperative
C)
Negative
D)
Assertive
The sentence gives a command or instruction: "Drive to the roundabout and then turn left." Such sentences are imperative sentences. It is not exclamatory because it does not express sudden emotion, not negative because it does not contain a negation, and not assertive because it is not merely stating a fact.
Something which can not be avoided.
A)
Unavoidable
B)
Inimitable
C)
Inevitable
D)
Unevitable
The phrase "something which cannot be avoided" means "unavoidable." Option (a) matches this meaning exactly.
(b) Inimitable means something that cannot be imitated, not avoided.
(c) Inevitable means certain to happen, which is close in meaning, but the best direct match for "cannot be avoided" in this vocabulary question is unavoidable.
(d) Unevitable is not a correct English word.
Retrogression (Opposite meaning)
A)
Retardation
B)
Development
C)
Progress
D)
Impunity
Retrogression means going backward or deterioration. The opposite is progress, which means forward movement or advancement. Retardation is slowing down, development is growth but not the direct antonym here, and impunity means exemption from punishment.
The phrase “grabbing, self-seeking” means
A)
Cruel and vicious
B)
Blunt and arrogant
C)
Selfish and possessive
D)
Proud and assertive
“Grabbing” in this context means greedy or grasping, and “self-seeking” means concerned mainly with one's own advantage. Together, the phrase conveys the idea of being selfish and possessive. The other options do not match this meaning: cruel/vicious, blunt/arrogant, and proud/assertive are different attitudes.
You have to believe in yourself if you expect to be successful. (Identify part of speech of 'yourself')
A)
Pronoun
B)
Adverb
C)
Verb
'Yourself' is a reflexive pronoun. It refers back to the subject 'you' and emphasizes the person doing the action. Therefore, the correct part of speech is Pronoun. 'Adverb' and 'Verb' are incorrect because 'yourself' does not modify a verb/adjective/adverb, nor does it show an action.
To get into hot waters
A)
to bein the middle of the sea
B)
to loose patience
C)
to get into trouble
D)
to be of hot temperament
The idiom "to get into hot water(s)" means to be in trouble or difficulty. So option (c) is correct. Option (a) is literal and unrelated, option (b) means to lose patience, and option (d) refers to temperament, not trouble.
Has anyone seen my torch?
A)
Interrogative
B)
Affirmative
C)
Assertive
D)
Negative
The sentence "Has anyone seen my torch?" asks a question, so it is an interrogative sentence. It is not affirmative/assertive because those make statements, and it is not negative because it does not contain a negative word like 'not'.
Our overbearing boss expects us to show UP ahastiadss
A)
now and then
B)
onceina blue moon
C)
safe and sound
D)
at the drop ofa hat
The phrase "show up at the drop of a hat" means to appear or be ready immediately, without delay, especially when expected by someone overbearing. Among the options, this matches the sentence best.
(a) "now and then" = occasionally
(b) "once in a blue moon" = very rarely
(c) "safe and sound" = unharmed
(d) "at the drop of a hat" = instantly / without hesitation
Pizza, which most people love is not very healthy. (Identify the clause of the underlined words)
A)
noun clause
B)
adverb clause
C)
adjective clause
D)
independent clause
The underlined words are likely "which most people love". This is a relative clause introduced by "which" and it modifies the noun "Pizza". A clause that describes a noun or pronoun is an adjective clause. It is not an adverb clause because it does not show time, place, reason, or manner, and it is not a noun clause because it is not functioning as a noun. It is also not independent because it cannot stand alone as a complete sentence.
Sedentary means
A)
Weak
B)
Elderly
C)
Inactive
D)
Fragile
“Sedentary” means involving much sitting and little physical activity, i.e., inactive. The other options do not match the meaning: weak = lacking strength, elderly = old, and fragile = easily broken or delicate.
To read between the lines
A)
to read cautiously
B)
to understand the hidden meaning
C)
to read the fine print
D)
to read aloud
"To read between the lines" means to understand the implied or hidden meaning, not just the literal words. Option (b) is correct. Option (a) means reading carefully, (c) refers to reading small or detailed print, and (d) means reading out loud.
Pressure of refrigerant in the evaporator should be
A)
Equal to the atmospheric pressure
B)
Less than the atmospheric pressure
C)
Greater than the atmospheric pressure
D)
None of these
In a refrigeration system, the evaporator operates at a low pressure so that the refrigerant can boil at a low temperature and absorb heat from the space being cooled. Therefore, the pressure in the evaporator is kept below atmospheric pressure (in many systems) or generally at a low suction pressure. Hence, option (b) is correct. Options (a) and (c) are not generally correct for the evaporator, and (d) is incorrect because a correct choice is available.
With the increase in the excitation current of synchronous motor the power factor of the motor will
A)
improve
B)
decrease
C)
remain constant
D)
depend on other factors
In a synchronous motor, increasing the field excitation increases the internal emf. Starting from under-excitation (lagging power factor), as excitation is increased the motor power factor improves toward unity, and with further over-excitation it becomes leading. Hence, with increase in excitation current, the power factor improves. Options (b) and (c) are incorrect because the power factor does not simply decrease or remain constant.
Speed control of induction motor can be effected by varying
A)
Flux
B)
Voltage input to stator
C)
Keeping rotor coil open
D)
None of these
The speed of an induction motor depends mainly on supply frequency, number of poles, and slip. In practice, one way to control speed is by varying the stator supply voltage, which changes the developed torque and operating slip, thereby affecting speed.
Why the others are incorrect:
- (a) Flux: Flux is not the usual direct method for induction motor speed control in this form.
- (c) Keeping rotor coil open: This is not a speed control method; it would prevent proper motor operation, especially in wound-rotor motors.
- (d) None of these: Incorrect because stator voltage variation is a valid speed control method.
A thyristor can be termed as
A)
DC switch
B)
AC switch
C)
Both (a) and (b) are correct
D)
Square-wave switch
A thyristor (SCR) is a semiconductor switch that can be used in both DC and AC circuits. In DC applications, it acts as a controllable DC switch because once triggered it remains ON until the current falls below the holding current. In AC applications, it also functions as an AC switch since it naturally turns OFF at the AC zero crossing. Hence, both (a) and (b) are correct.
Synchronous motor can operate at
A)
Lagging power factor only
B)
Leading power factor only
C)
Unity power factor only
D)
Lagging, leading and unity power factor only
A synchronous motor can be operated at different power factors by adjusting its field excitation.
- Under-excited: it draws lagging reactive power, so it operates at lagging power factor.
- Normally excited: it can operate at unity power factor.
- Over-excited: it supplies reactive power to the system, so it operates at leading power factor.
Therefore, a synchronous motor can run at lagging, leading, and unity power factor.
For minimum weight of the transformer, the iron weight should be __ the weight of the copper:
A)
More than
B)
Equal to
C)
Less than
D)
None of these
For minimum weight of a transformer, the weight of iron should be less than the weight of copper. In a well-designed transformer, the core (iron) is kept compact, while the copper windings contribute more to the total weight. Hence the correct choice is 'Less than'.
The advantage of the tachometer speed control method for d.c. motors is that it senses
A)
back emf
B)
armature current
C)
armature voltage
D)
speed
A tachometer is a speed-sensing device mounted on the motor shaft. In tachometer feedback speed control of a d.c. motor, the actual motor speed is measured directly and fed back for control. Hence, the method senses speed. It does not sense back emf, armature current, or armature voltage directly.
Choose the correct order, from left to right, in which these parts should be placed in order to form the object.
A)
1 2 3 4
B)
2 1 3 4
C)
2 1 4 3
D)
1 4 3 2
The correct left-to-right arrangement is 2 1 3 4, so option **b** is correct. The parts must be placed so that the visible edges and contours continue smoothly from one piece to the next; only this sequence produces a consistent overall shape without mismatched projections or gaps. Option **a (1 2 3 4)** and **d (1 4 3 2)** place the first pieces in an order that breaks the natural edge continuity, while **c (2 1 4 3)** swaps the last two parts and does not match the required progression of the shape.
