Indian Navy Agniveer Mock Test - 9 - Indian Navy Agniveer MCQ

The correct answer is 'The government has launched a massive tribal welfare program in Jharkhand'.

Key Points

• In Active Voice, a sentence emphasizes the subject, performing an action.
• In Passive Voice, a sentence emphasizes the action or the object of the sentence.
• The given sentence is in the passive voice, and 'A massive tribal welfare program' is the subject, and 'the government' is the object.
• When we convert this sentence into an active voice, the subject 'A massive tribal welfare program' of the passive voice becomes the object, the object 'the government' becomes the subject.
• The passive format "has + been + V3 (launched)" should be converted into the active format "has + V3 (launched)".
• This is the active and passive voice rule for the present perfect tense.

Hence, the correct answer is option 1.
Additional Information

• Verbs of passive format have a different set of tenses (*V3 - Past participle or Third form of the Verb) as given below in the table:
  

The correct answer is "You're a great speaker, James, so you might win the competition."

Key Points

• 'You're' is the short form of 'You are'.
• We use a comma(,) before a coordinating conjunction (and, but, yet, so, or, nor, for) when it joins two complete ideas (independent clauses). It indicates a short pause.
• We use full stop(.) to end a sentence. It indicates a longer pause.
  • Example: I love coffee, but my sister prefers tea.
• Hence, the correct answer is option 3.

Correct Sentence: "You're a great speaker, James, so you might win the competition."

Here the correct answer is Superman was created by Marvel Comics.

Key Points

• The above-given sentence is in the active voice.
• We need to change it in the passive voice.
• The following steps are required to change the given sentence into passive voice:-
• The subject 'Marvel Comics' of the active voice will become the object of the passive voice.
• The object 'Superman' of the active voice will become the subject of the passive voice.
• The tense(simple past tense) will change according to the following structure:-
  • Active Voice - Subject + (did + V1) or (V2) + Object.
  • Passive Voice - Object + was/were + V3 + by + Subject.
• ​Thus, the correct answer is Option 1.
  

Therefore, the correct passive voice is Superman was created by Marvel Comics.

Additional Information

• When we convert active voice to passive voice, three things need to be kept in mind:-
  • Change object into subject.
  • Change subject into object.
  • Always use the third form of the verb in the passive voice.
  • Use 'by' before the new object.

The correct answer is 'out'.

Key Points

• The phrase 'turn out to be' is used to mean to happen in a particular way or to have a particular result, especially an unexpected one.
• By reading the above-given sentence, we can see the most likely/ intended meaning of the given sentence is that he was found to be a gangster, which apparently was not expected.
• So, the correct choice for the word to fill the blank is 'out' and the correct sentence: 'He turned out to be a gangster.'

Hence, Option 1 is the correct answer.

Additional Information

• turn (something) off ⇒ switch off.
• turn (something) on ⇒ switch on; make someone feel interested or excited.

The correct answer is "How was such a heavy ball thrown by Raman to the other side of the building?"

Key Points

• We have to change the above sentence to passive form.
• In Active Voice, a sentence emphasizes the subject.
  • In Passive Voice, a sentence emphasizes the action or the object of the sentence.
  • The given sentence is in the active voice and 'Raman' is the subject and 'heavy ball' is the object.
  • When we convert this sentence into passive voice, the subject 'Raman' of the active voice becomes the object.
  • The object 'the heavy ball' becomes the subject.
  • The passive form rule 'was + V3 (sent)' should be used.

Thus, the correct answer is How was such a heavy ball thrown by Raman to the other side of the building?

The correct answer is 'Bolster'.

Key Points

• Let's explore the meaning of the marked word and the given word.
  • Boost: help or encourage (something) to increase or improve.
    • Example: The new resort area has boosted tourism.
  • Bolster: support or strengthen.
    • Example: Timman needs to win a game to bolster his confidence.

• Placate: make (someone) less angry or hostile.
  • Example: These changes did little to placate the unions.
• Shackle: restrain; limit.
  • Example: Industrial progress is being shackled by a mass of regulations.

The correct answer is "of, on".
Key Points

• This sentence implies that cyclists have substituted taking their bikes outdoors.
• So, the correct preposition to be filled in the first blank is "of" because the correct preposition is "Instead of".
• "Instead of" means in place of; as a substitute for or alternative to something.
  • Example: I’ll have a piece of cake instead of cookies.
• Preposition "on" is correct to fill in the second blank.
• "Hook on" means very interested and enthusiastic about something.
  • Example: She got hooked on the show after watching one episode.
• Hence, option 2 is correct.

The correct answer is 'tries'.

Key Points

• The word 'always' hints that the sentence is in Present Indefinite Tense.
• If the subject is singular, the structure of Present Indefinite tense is: Subject + (Verb+s/es) + object.
  • Ex: Ayush plays football every Sunday.
• The subject of the sentence is singular, so Verb+s/es will be used.
• Therefore, the correct word that fits the blank is 'tries'.
• Hence, option 2 is the correct answer.

Complete sentence - Zeba always tries to prove that the moon revolves around the earth.

Additional Information

• The tense form of the other options are as follows -
  • tried - simple past tense
  • was trying - past continuous tense
  • is trying - present continuous tense

The correct answer is 'have never seen , offer.'

Key Points

• Let us start with the second blank.
• We can see a plural subject "founders" is present before the blank.
• Now, according to Subject-Verb agreement, a plural subject takes a plural verb.
• "Has offered", "Is offering" and "offers are singular verbs.
• So, options 1, 2 and 3 can be ruled out.
• Never means 'at no time' and is a negative term, used in affirmative constructions (to avoid double negatives).
• Ever means 'at any time' and is generally not used in affirmative sentences.
• The given sentence is an affirmative sentence, so we must use "never" in the sentence.
• Following all these rules, the correct answer is Option 4.
  

​Correct sentence: Joe Merino is a popular store like you have never seen before and its founders offer you the perfect shopping pleasure.

CONCEPT:

According to Bohr's model of an atom, the energy of the transition in the different orbits is written as;

ΔE=13.6[1n12−1n12]

or we also can write the energy of the different transitions as;

E_n = 

Here, n is the principal quantum number for different transitions.

and frequency is written as;

E = hf

here, E is the energy, h is the Planck's constant, and f is the frequency.

EXPLANATION:

To calculate the frequency maximum in the transitions we use;

and

At n = 1 ,

⇒E₁ = -13.6 eV

At n = 2 ,

E₂ = - 3.4 eV

At n = 3,

E₃ = -1.51 eV

at n = 4

E₄ = -0.85 eV

and n = 5

E₅ = 0.544 eV

As we see that from n = 2 to n = 1 the transition of energy is high and from equation (1) when energy increased the frequency will also increase.

Therefore from n = 2 to n = 1 transitions is having a maximum frequency.

The transition of the frequency is shown in the figure below;

Hence, option 1) is the correct answer.

CONCEPT:

When resistance is in series we have;

CALCULATION:

Since both the diodes will be reverse biased, the respective branches will be open-circuited, and the remaining resistances, i.e. 5 Ω, 10 Ω, 5 Ω, & 10 Ω will be in series.

As we can see in this figure, the resistances are in series, therefore;

⇒

⇒

According to Ohm's law, we have;

V = IR

⇒

⇒

⇒ i = 0.3 A

Hence option (2) is the correct answer.

The correct answer is 1 and 3 only.

The correct answer is Fats.

Key Points

• Fats have the highest gross calorific value.
  • The digestion of fats starts from the small intestine.
  • Bile from the liver makes the solution alkaline and breaks down the big fat globules into smaller ones.
  • Lipase from the pancreas breaks down the fats further in the small intestine.
  • Intestinal juice completes the process of digestion of fats and is absorbed.
  • Fats are found in vegetable oils, animal, fats and other foods like nuts.

CONCEPT:

• The ac circuit containing the capacitor, resistor, and inductor is called an LCR circuit.
• For a series LCR circuit, the total potential difference of the circuit is given by:

Where VR = potential difference across R, VL = potential difference across L and VC = potential difference across C

• For a series LCR circuit, Impedance (Z) of the circuit is given by:

Where R = resistance, XL =induvtive reactance and XC = capacitive reactive

• When the LCR circuit is set to resonance, the resonant frequency is

CALCULATION:

• From the above, it is clear that the resonant frequency is given by

• From the above equation, it is clear that the resonant frequency is independent of resistance, so if the value of R is decreased by 20 Ω then there will be no change in the value of resonant frequency. Therefore the correct answer is option 4.

Concept-

• Enzymes are a substance that acts as a catalyst in organisms it regulates the rate at which chemical reactions proceed without itself being altered in the process.
• A catalyst is a substance that is added to increase the reaction rate of the reaction without getting consumed in the process.
• They are high molecular weight compounds made up principally of chains of amino acids linked together by peptide bonds.
• Enzymes can be denatured and precipitated with salts, solvents, and other reagents.
• Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by a chemical reaction. The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start.

Explanation-

• Vitamins are called micronutrients because they are needed in only very small quantities.
• Vitamins are made up of carbon, hydrogen, and oxygen.
• Vitamins are of two types:
  • Water-soluble vitamins - B, C

Explanation:

Plotting the function f(x) , we get,

As it can be seen from the figure that the maximum value of graph is at x=3

i.e. the function attains its maximum value only at x=3 (which is at point B in the graph)

As on putting x = 3, f(x) = 4 ⇒the maximum value of function.

And by looking at the graph, its minimum value is at x=0.

As on putting x = 0, f(x) = 1 ⇒the minimum value of function.

Concept Used:

Greatest Integer Function: (Floor function)

The function f (x) = [x] is called the greatest integer function and means greatest integer less than or equal to x i.e [x] ≤ x.

The domain of [x] is R and range is I, where R is the set of real numbers and I is the set of integers.

From the graph, we can say that the function is discontinuous at every integer.

The function f ( x )= [x] is continuous for all x , except integral values of x.

Calculation:

f(x) = x + [x]

So for this domain,

x ∈ R

Referring to the graph, the function f ( x ) = x + [x] is continuous for all x, except integral values of x so f(x) will not be continuous and differentiable for x ∈ R

So,

Hence,  does not exist.

Concept:

If a function is continuous at x = a, then L.H.L = R.H.L = f(a).

Left hand limit (L.H.L) of f(x) at x =  

Right hand limit (R.H.L) of f(x) at x =

Calculation:

Given: f(x)

Hence L.H.L = R.H.L = 0

For a function to be continuous at x = 0, 

L.H.L = R.H.L = function value at x = 0

Given that the value of the function is 0 at x = 0.

∴ f(0) = L.H.L = R.H.L = 0

The correct answer is 0.

Concept:

Calculation:

Differentiating both sides with respect to x,



∴ The correct answer is option (3).

Concept:

Calculation:

Since, 

Adding (i) and (ii),

∴ The correct answer is option (3).
