#### Ques 31: Which one of the following is an example of a technological barrier in communication ?

• Complexity of ideas
• Low bandwidth of internet
• Personal attitude towards technology
• Physical locations of communicators

Communication
Technological barrier : low bandwidth of internet is example of technological barrier.
Psychological barrier : Complexity of ideas and personal attitude towards technology is an example psychological barrier.
Geographical barriers : physical locations of communicators is a geographical barrier.
Semantic barrier : communication barriers related to language and the meaning of the words.

#### Ques 32: Given below are two statements Statement I : the compound interest on 280 for 18 months at 10% per annum is 44.3. statement it : at 5.6% rate of simple interest, a certain sum will be doubled in 15 years In light of the above statements, choose the correct answer from the options given below :

• Both Statement I and Statement II are false
• Both Statement I and Statement II are true
• Statement I is false but Statement II is true
• Statement I is true Statement II is false

Mathematical Reasoning and Aptitude
Statement I
Amount = 280 (1+10/100) (1+5/100)
= 280 (11/10)21/20) = 323.4
Compound Interest = Amount – Principal
= 323.4 – 280 = 43.4
Statement II
This question is based on simple interest, so interest will be 5.6 on 100 every annum. In 15 years, total SI will be 15⨯5.6 = 84. Thus, amount will not be doubled, but much less than that.
Thus, both statements are not correct.

#### Ques 33: The Post Office protocol is

• Protocol used for sending emails
• Protocol used for transfer of files from one computer to another computer
• Protocol used to handle email attachments
• Protocol used when receiving emails from the email server

Information and Communication Technology In computing, the Post Office Protocol is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. POP version 3 is the version in common use.
The Post Office Protocol provides access via an Internet Protocol (IP) network for a user client application to a mailbox (maildrop) maintained on a mail server. Thus, the protocol used when receiving emails from the email server.

#### Ques 34: CBCS is

• Choice Based Credit System
• Credit Based Choice Scores
• Criteria based Choice System
• Criteria Based Creditable Scores

Higher Education System
CBCS stands for the choice-based credit system.
CBCS grading systems surpass the ‘conventional percentage’ and grading means to evaluate a student’s academic skills. CBCS follows a more standardized way of assessment and examination management. CBCS software grading system is uniform across all educational institutes. It follows the semester pattern and not the annual examination pattern.
UGC also follows a 10-point grading system, with 0 being absent/fail and 10 being outstanding.
Evaluation in choice Based Credit System in Higher Education

#### Ques 35: mooKIT platform uses, an open source content management system.

• DRUPAL
• JOOMLA
• Moodle
• SAKAI

Teaching Aptitude/ICT
DRUPAL : Drupal is a free software package that allows an individual or a community of users to easily publish, manage and organize a wide variety of content on a website.
Drupal is used by mooKIT platform for open source content management system.
JOOMLA : This uses to build, organize, manage and publish content for websites, blogs, Intranets and mobile applications.
Moodle : Moodle is a free and open-source learing management system (LMS) written in PHP and distributed under GNU (General Public licence)]. Moodle is used for blended learning, distance education, flipped classroom and other e-learning projects in schools, universities, workplaces and other sectors
SAKAI : Sakai is a free, community source, educational software platform designed to support teaching, research and collaboration. Systems of this type are also known as Course Management Systems (CMS), Learning Management Systems (LMS), or Virtual Learning Environments (VLE).

#### Ques 36: Following are some statements regarding file transfer protocol (FTP). Choose the correct statements A. It is used to access the world wide wed (www) B. It is used to download data from file servers C. It is used for very small files D. Files are transferred from one device to another Choose the correct answer from the options given below :

• A and B only
• A and C only
• B and C only
• B and D only

Information and Communication Technology
File Transfer Protocol (FTP) : FTP is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built a client0server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password. FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP) for secure transmission.

#### Ques 37: According to Urie Bronfenbrenner’s biological model of human development, microsystem constitutes A. Immediate family B. School C. Beliefs D. Customs E. Neighbourhood Choose the correct answer from the options given below :

• A,B and E only
• A,B and C only
• A,C and E only
• C,D and E only

People, Development and Environment
According to Urie Bronfenbrenner’s biological model of human development, microsystem constitutes immediate family, schools and neighbourhood.

#### Ques 38: Given below are two statements Statement I : Small amount of atmospheric Nitrogen dioxide NO2 is produced from polluting sources Statement II : Most of the atmospheric NOW is produced due to photochemical reactions in the atmosphere In light of the above statements, choose the most appropriate answer from the options given below :

• Both Statement I and Statement II are correct
• Both Statement I and Statement II are incorrect
• Statement I is correct but Statement II is incorrect
• Statement I is incorrect but Statement II is correct

People, Development and Environment
Statement I : small amount of atmospheric Nitrogen dioxide is produced from polluting sources.
NO2 is an intermediate in the industrial synthesis of nitric acid. It is largely used in the production of fertilisers also. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantity.
Statement II : Most of the atmospheric NO2 is produced due to photochemical reactions in the atmosphere.
Nitrogen dioxide, NO2, present in air is known to be photochemically active due to the presence of an unpaired electron. NO2 molecule reaches a higher level of energy when it absorbs a photon of light with energy, which converts the ground state molecule to electronically excited state molecule. NO2, Ozone and PAN show photochemical reactions and photochemical smog is formed.

#### Ques 39: The average of ten number is 7. If each number is multiplied by 11, then the average of the new set of numbers is :

• 72
• 77
• 78
• 82

Mathematical Reasoning and Aptitude
If each averaged number, X’ is multiplied by an another number, Y, then new average will be multiplication of those numbers, that is X.Y. thus, answer to this question will be 7⨯11 = 77.

#### Ques 40: Which of the following water borne diseases may be caused by virus, bacteria and protozoa ?

• Cholera
• Diarrhea
• Hepatitis
• Typhoid

People, Development and Environment
Diarrhoea is a type of waterborne disease which is caused by virus bacteria and protozoa. The main symptoms of diarrhea are frequent loose, watery stools and a pressing urge to have a bowel movement. The most common causes of acute and persistent diarrhea are infection, travelers’ diarrhea, and side effects of medicines. Many viruses cause diarrhea, including norovirus link and rotavirus link. Viral gastroenteritis is a common cause of acute diarrhea.
