83. Jacquard loom is used for making :

Correct Answer: (c) complex patterned weave
Solution:

The Jacquard loom is used for making fabrics with *complex pattern weaves*. Unlike conventional looms limited to basic weaves like plain or twill, the Jacquard loom employs a system of punched cards or electronic controls to manipulate individual warp threads, enabling intricate designs and patterns such as florals, geometrics, and elaborate scenes. It’s a pivotal tool in textile production, especially for crafting brocade, damask, and tapestries, owing to its capacity to weave detailed and diverse patterns with ease and precision.

84. Examples of condensation polymerization are :

(A) Acrylic      (B) Modacrylic
(C) Nylon        (D) Elastomers
(E) Polyester
Choose the correct answer from the options given below : 

Correct Answer: (b) (C), (D) and (E) Only
Solution:

The examples of condensation polymerization provided are Nylon, Elastomers, and Polyester. Condensation polymerization involves the formation of polymers through the reaction between monomers with the elimination of small molecules, such as water or hydrogen chloride. In the case of nylon, elastomers, and polyester, this process occurs as monomers react, forming long chains while releasing water molecules or other byproducts. This chemical reaction leads to the creation of the respective polymer structures, each with its distinct properties and applications.

85. Which of the following are characteristics and features of communication?

(A) It involves the exchange of ideas, facts and opinions.
(B) It is a continuous process.
(C) It is verbal and non verbal.
(D) It is synchronous and asynchronous in nature.
(E) It is always verbal.
Choose the correct answer from the options given below : 

Correct Answer: (d) (A), (B) and (C) Only
Solution:

The correct answer is A, B, and C.
(A) It involves the exchange of ideas, facts, and opinions: Communication encompasses the sharing of thoughts, information, and perspectives between individuals or groups. This exchange can involve conveying ideas, stating facts, or expressing opinions.
(B) It is a continuous process: Communication is not limited to a single interaction but rather occurs continuously over time. It involves ongoing exchanges and interactions between individuals or parties.
(C) It is verbal and nonverbal: Communication can take place through both verbal means, such as spoken or written words, and nonverbal means, such as body language, facial expressions, gestures, and tone of voice. These characteristics highlight the diverse and multifaceted nature of communication, which involves the exchange of various forms of information and occurs continuously through both verbal and nonverbal channels.
Option (D) is incorrect because while communication can occur synchronously (in real-time) or asynchronously (with a time delay), this aspect is not necessarily a characteristic of communication itself, but rather a feature of how communication can be facilitated.
Option E is incorrect because communication is not always verbal; it can involve nonverbal cues as well.

86. Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Post menopausal women are at three times the risk of developing cardiovascular diseases than premenopausal women.
Reason (R) : Women in reproduction age including premenopausal women have female sex hormones specially estrogen which protects against cardiovascular diseases. Estrogen relaxes the arteries and promotes good cholesterol. Estrogen declines as the menopause approaches. In the light of the above statements, choose the most appropriate answer from the options given below:

Correct Answer: (a) Both (A) and (R) are correct and (R) is the correct explanation of (A).
Solution:

Both Assertion and Reason R are correct and Reason (R) elucidates that premenopausal woman face high risk of cardiovascular diseases because estrogen as memofause approach.

87. Which one of the following is a fabric tunnel?

Correct Answer: (c) Casing
Solution:

A casing refers to a fabric tunnel created by folding over and stitching down a portion of the fabric to form a tube-like structure. This tunnel allows for the insertion of elastic bands, drawstrings, ribbons, or other materials that can be adjusted or moved within the garment.

88. Window treatments containing only sheers are:

(A) Glass curtain     (B) Bamboo shades
(C) Shoji screen       (D) Sash curtain
(E) Quilt shade
Choose the correct answer from the options given below :

Correct Answer: (a) (A) and (D) Only
Solution:

Glass curtain:- A glass curtain typically consists of sheer or semi-transparent materials that allow light to pass through while providing some level of privacy. Sheer fabrics are commonly used in glass curtains to diffuse light and create an airy atmosphere.
Sash curtain:- Sash curtains are often made of lightweight and translucent fabrics, including sheers. They are designed to filter light while maintaining privacy, making them suitable for window treatments in various settings.
Both of these window treatments commonly incorporate sheer materials, which allow diffused light to enter the room while offering a level of privacy.

89. Below is given a list of teaching methods and approaches. Which among them are individualised approaches?

(A) Demonstration method
(B) Modular approach based learning
(C) Programmed learning method
(D) Personalized teaching
(E) Collaborative method
Choose the correct answer from the options given below :

Correct Answer: (b) (B), (C) and (D) Only
Solution:

Individualized approaches in teaching focus on tailoring instruction to the needs and pace of individual learners.
The individualized approaches among the given options are:
(B) Modular approach based learning
(A) Demonstration Method
(C) Programmed learning method
(D) Personalized teaching
These methods emphasize adapting the learning process to the specific needs and abilities of each learner.

90. Match List-I with List-II


Correct Answer: (a)
Solution:

Z-test: A statistical test used to determine whether the means of two populations are different when the population variances are known and the sample size is
large.
t-test : A statistical test used to determine whether there is a significant difference between the means of two groups based on a sample of data.
Chi-square test: A statistical test used to determine whether there is a significant association between two categorical variables. It compares the observed frequencies to the expected frequencies.
F-test: A statistical test used to compare the variances of two samples to determine if they are significantly different from each other. It is often used in analysis of
variance (ANOVA) to test the equality of means across multiple groups.
