SSC Practice Test 1 — Questions and Answers

Question 1: Choose the word that cannot be constructed with the letters of the given word from the list of alternatives: "ENVIRONMENT"

ENTER
EMINENT
MOVEMENT
ENTRANCE (Correct answer)

Correct answer: ENTRANCE

The word 'ENVIRONMENT' contains the letters E, N, V, I, R, O, M, T. The word 'ENTRANCE' requires the letters 'A' and 'C', neither of which are present in 'ENVIRONMENT'. Therefore, 'ENTRANCE' cannot be constructed from the letters of the given word.

Question 2: Which of the following words can be prefixed with a single letter to create completely new terms? (In all five words of each, t he same letter must be prefixed.) EAT OUR IS AS AT

H (Correct answer)
C
S
B

Correct answer: H

When the letter 'H' is prefixed to each of the given words, they form new, meaningful English words: HEAT, HOUR, HIS, HAS, and HAT. No other single letter from the options (C, S, B) can be prefixed to all five words to create valid terms.

Question 3: The following symbols are used in the questions: Δ = equal to ⊗ = not equal to + = greater than ⊘ = less than - = not less than O = not greater than Read the question and select the appropriate answer. If X - Y - Z, it doesn't

X⊗YΔZ
X⊘Y+Z (Correct answer)
XOY+Z
X⊘Y−Z

Correct answer: X⊘Y+Z

The statement X - Y - Z translates to 'X is not less than Y' (X ≥ Y) and 'Y is not less than Z' (Y ≥ Z). This implies X ≥ Y ≥ Z. Option B, X⊘Y+Z, translates to 'X is less than Y' (X < Y) and 'Y is greater than Z' (Y > Z). The condition X < Y directly contradicts X ≥ Y, making option B impossible if X - Y - Z is true.

Question 4: L,M,N,O,P,Q are the six members of a family that includes two married couples. P is a teacher who is married to N and Q's mother, a doctor. L is the wife of M, the lawyer. P has a son and a grandson. One of the two married ladies is a stay-at-home mom. In the family, there is also a student and a male engineer. Which of the following statements regarding the family's granddaughter is true?

She is a doctor
She is a lawyer
She is a engineer
She is a student (Correct answer)

Correct answer: She is a student

Based on the family structure deduced (P and N are grandparents, Q is their son, and O is Q's daughter, making her the granddaughter), and the remaining occupations, O is identified as the student. P is a teacher, N a doctor, M a lawyer, L a stay-at-home mom, and Q a male engineer. This leaves the student role for O, the granddaughter.

Question 5: Six students are seated on the ground: L,M,N,O,P,Q. The Pearl House is made up of L and M, whereas the Sapphire House is made up of everyone else. O and Q are tall, whereas the rest of the group is short. N and O are wearing glasses, whereas the rest of the group is not. Which Sapphire house girl is tall and wears glasses?

N
O (Correct answer)
M
L

Correct answer: O

Let's break down the criteria: Sapphire House members are N, O, P, Q. Tall students are O, Q. Students wearing glasses are N, O. Combining these, the Sapphire house member who is tall and wears glasses is O. O is in Sapphire House, is tall, and wears glasses, fitting all conditions.

Question 6: Which of the following words can be suffixed with a single letter to produce new words? BATH HAT BAR BAT PIN

E (Correct answer)
A
D
B

Correct answer: E

When the letter 'E' is suffixed to each of the given words, they form new, meaningful English words: BATHE, HATE, BARE, BATE, and PINE. No other single letter from the options (A, D, B) can be suffixed to all five words to create valid terms.

Question 7: FARMER is written as MAFMRE in a given code; which word will be written as GIVALEL in that code?

VIALEGL
AIGALE
VELAIGL
None of the above (Correct answer)

Correct answer: None of the above

The coding pattern for FARMER (6 letters) to MAFMRE involves a specific rearrangement of letters. However, the word to be decoded, GIVALEL, has 7 letters. Since the length of the word to be decoded does not match the length of the word used to establish the coding pattern, the given pattern cannot be directly applied. Therefore, none of the provided options can be the correct decoded word.

Question 8: If you start running from a point in the north and run 4 kilometers, then turn left and run 5 kilometers, then turn left again and run 5 kilometers, then turn left again and run another 6 kilometers, and finally turn left and run 1 kilometer. then, using this information, respond to the following question. Which direction will you have to run if you need to get back to where you started from the finish line?

South
East
West (Correct answer)
North

Correct answer: West

Tracing the path: 4km N to (0,4), then 5km W to (-5,4), then 5km S to (-5,-1), then 6km E to (1,-1), and finally 1km N to (1,0). The finish line is at (1,0) and the starting point is (0,0). To return from (1,0) to (0,0), one must move 1 unit to the left, which corresponds to the West direction.

Question 9: Determine which pair 'does not' have the same relationship as the capitalized pair: WORDS : ETYMOLOGY

PSYCHOLOGY : MIND
ANATOMY : BODY
PHILOSOPHY : LANGUAGE (Correct answer)
ARCHEOLOGY : ANTIQUES

Correct answer: PHILOSOPHY : LANGUAGE

The relationship in 'WORDS : ETYMOLOGY' is that Etymology is the study of words. Similarly, Psychology is the study of the mind, Anatomy is the study of the body, and Archeology is the study of antiques. However, Philosophy is a broad field of inquiry, not specifically 'the study of language'; Linguistics is the study of language. Thus, 'PHILOSOPHY : LANGUAGE' does not share the same direct 'study of' relationship.

Question 10: Find the odd one out by arranging the letters of each group to form a meaningful word.

VIDEID (Correct answer)
ORFU
VEENS
GHIET

Correct answer: VIDEID

Unscrambling the letters reveals the following words: VIDEID becomes DIVIDE, ORFU becomes FOUR, VEENS becomes SEVEN, and GHIET becomes EIGHT. Options B, C, and D all form numbers. Option A, DIVIDE, forms a verb, making it the odd one out among the group of numbers.

Question 11: Determine which of the given options will be a member of that class's group. Lucknow, Patna, Bhopal, Jaipur ?

Shimla (Correct answer)
Mysore
Pune
lndore

Correct answer: Shimla

Lucknow, Patna, Bhopal, and Jaipur are all capital cities of Indian states (Uttar Pradesh, Bihar, Madhya Pradesh, and Rajasthan, respectively). Among the given options, Shimla is also a capital city, specifically of Himachal Pradesh. Mysore, Pune, and Indore are significant cities but not state capitals.

Question 12: The Indian parliament enacted the Environment (Protection) Bill in:

1986 (Correct answer)
1985
1976
1983

Correct answer: 1986

The Indian Parliament enacted the Environment (Protection) Act in 1986. This landmark legislation was a comprehensive measure to protect and improve the environment, following the decisions made at the United Nations Conference on the Human Environment in Stockholm in 1972.

Question 13: When is the International "Yoga Divas" Day?

21st May
21st June (Correct answer)
21st July
25th April

Correct answer: 21st June

The United Nations General Assembly declared June 21st as the International Day of Yoga in 2014. This date was chosen because it is the summer solstice in the Northern Hemisphere, the longest day of the year. This day holds special significance in many cultures and is considered auspicious for spiritual practices like yoga.

Question 14: Photochemical smog is caused by a reaction between:

High concentration of NO2, O3 and CO in the evening
NO2, O3 and peroxyacetyl nitrate in the presence of sunlight (Correct answer)
CO, O2 and peroxyacetyl nitrate in the presence of sunlight
CO, CO2 and NO at low temperature

Correct answer: NO2, O3 and peroxyacetyl nitrate in the presence of sunlight

Photochemical smog forms when sunlight reacts with nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the atmosphere. Key components include nitrogen dioxide (NO2), ozone (O3), and peroxyacetyl nitrate (PAN). Sunlight provides the energy for these chemical reactions, leading to the formation of secondary pollutants that characterize this type of smog.

Question 15: The total energy of a missile launched at a velocity less than the earth's escape velocity is:

Positive
Zero
Negative (Correct answer)
Either positive or negative

Correct answer: Negative

For an object to escape Earth's gravitational pull, its total mechanical energy (kinetic + potential) must be zero or positive. If a missile is launched with a velocity less than the escape velocity, its kinetic energy is insufficient to overcome the negative gravitational potential energy. Therefore, its total energy remains negative, indicating it is still gravitationally bound to Earth.

Question 16: Who was the first person to discover an antibiotic?

Louis Pasteur
W. Fleming
C. Waksman
A. Fleming (Correct answer)

Correct answer: A. Fleming

Alexander Fleming, a Scottish physician and microbiologist, is credited with discovering penicillin in 1928. He observed that a mold, Penicillium notatum, inhibited the growth of Staphylococcus bacteria on a culture plate. This accidental discovery revolutionized medicine by leading to the development of the first widely used antibiotic.

Question 17: The Microbial Type Culture Collection Centre is located at:

Chandigarh (Correct answer)
Bangalore
Hyderabad
New Delhi

Correct answer: Chandigarh

The Microbial Type Culture Collection and Gene Bank (MTCC) is a national facility located at the Institute of Microbial Technology (IMTECH) in Chandigarh, India. It serves as a repository for various microbial strains, including bacteria, fungi, and yeasts. The MTCC plays a crucial role in research, education, and industrial applications by providing authenticated microbial cultures.

Question 18: Heavy metals earned their names because they have the following properties in comparison to other atoms:

Higher densities (Correct answer)
Higher atomic radii
Higher atomic numbers
Higher atomic masses

Correct answer: Higher densities

Heavy metals are generally defined by their relatively high densities compared to other elements. While they also tend to have higher atomic numbers and atomic masses, their characteristic 'heaviness' primarily refers to their density. This property is often linked to their compact atomic structure and strong metallic bonding.

Question 19: When one gene pair masks the action of the other, this is known as:

Epistasis
Mutation
Dominance (Correct answer)
None of the above

Correct answer: Dominance

Dominance in genetics refers to the phenomenon where one allele within a gene pair masks the expression of the other allele for the same trait. The allele that is expressed is called the dominant allele, while the masked allele is recessive. This means that even if an individual carries two different alleles for a gene, only the trait associated with the dominant allele will be observable in the phenotype.

Question 20: Choose the word that cannot be formed with the letters of the given word from the list of alternatives: CUMRSESOME

SOBER
ROME
MERCY (Correct answer)
MOUSE

Correct answer: MERCY

To determine which word cannot be formed, check if all letters in each alternative are present in the given word 'CUMRSESOME'. The word 'MERCY' cannot be formed because the letter 'Y' is not present in the original word. All other options (SOBER, ROME, MOUSE) can be constructed using the available letters.

Question 21: What is a single letter that may be prefixed to the following words to make new words? TABLE PILE TAB PRING TILL

B
C
H
S (Correct answer)

Correct answer: S

By adding the letter 'S' as a prefix to each of the given words, new valid English words are formed. These are STABLE, SPILE, STAB, SPRING, and STILL. No other single letter from the options can consistently form new words with all the given words.

Question 22: Xenobiotics are substances that are naturally resistant to microbial attack and are called such.

Persistent
Recalcitrant (Correct answer)
Biodegradable
All of the above

Correct answer: Recalcitrant

Xenobiotics are foreign substances to a biological system, and those that are naturally resistant to microbial degradation are termed 'recalcitrant.' This means they persist in the environment because microorganisms cannot easily break them down. Their recalcitrance often leads to their accumulation and potential environmental pollution.

Question 23: The Interest Liquidity Preference Theory was proposed by:

Adam Smith
David Ricardo
Alfred Marshall
J.M. Keynes (Correct answer)

Correct answer: J.M. Keynes

The Liquidity Preference Theory of Interest was developed by the renowned economist John Maynard Keynes. This theory posits that the interest rate is determined by the supply and demand for money, rather than by the supply and demand for loanable funds. Keynes argued that people prefer to hold liquid assets (money) and must be compensated with interest to part with their liquidity.

Question 24: The Noble Prize was awarded to Waksman for discovering:

Chloromycetin
Streptomycin (Correct answer)
Penicillin
Neomycin

Correct answer: Streptomycin

Selman A. Waksman was awarded the Nobel Prize in Physiology or Medicine in 1952 for his discovery of streptomycin. Streptomycin was the first effective antibiotic against tuberculosis, a devastating disease at the time. His work significantly advanced the field of antibiotics and saved countless lives.

Question 25: What method is employed to determine whether a data word contains an odd or even number of 1s?

Parity bit (Correct answer)
Carry bit
Sign bit
Zero bit

Correct answer: Parity bit

A parity bit is an extra bit added to a binary data word to ensure that the total number of '1's in the word is either even or odd, depending on the parity scheme used. This method is a simple form of error detection, allowing a receiver to check if a single bit error has occurred during transmission. If the parity check fails, it indicates data corruption.
