What is a major limitation of traditional data sharing (before Open Government Data initiatives, India)?

AToo much interoperability

BLack of standard formats and discoverability

CExcessive transparency

DOpen licensing issues

✓Answer: (B) Lack of standard formats and discoverability

Earlier, data was scattered, not machine-readable, difficult to access. OGD initiatives solved this by introducing standard formats, metadata, and centralized access.

Which of the following platforms provides APIs for accessing Indian government services and datasets?

ANDLI

BAPI Setu

CShodhganga

De-PG Pathshala

✓Answer: (B) API Setu

The API Setu platform enables secure API-based access to government data and services, supporting developers and digital innovation under Digital India.

The portal data.gov.in is associated with which initiative?

AOpen Government Data Platform India

BDigital Library of India

CNational Digital Health Mission

DBharatNet

✓Answer: (A) Open Government Data Platform India

The API Setu platform enables secure API-based access to government data and services, supporting developers and digital innovation under Digital India.

What is the role of metadata in data sharing?

ATo restrict access

BTo replace the dataset

CTo encrypt data

DTo describe and enable discovery of data

✓Answer: (D) To describe and enable discovery of data

Metadata provides context (who, what, when, how), making data findable and understandable.

14 April 2026

Which of the following is a recommended strategy for handling sensitive data?

APublishing all raw data openly

BIgnoring ethical approval

CUsing anonymisation and controlled access

DAvoiding data sharing completely

✓Answer: (C) Using anonymisation and controlled access

Sensitive data should be managed using anonymisation, restricted access, or secure environments, not avoided entirely.

13 April 2026

Which publisher integrates OA through platforms like BioMed Central?

ASpringer Nature

BElsevier

CSAGE Publications

DDe Gruyter

✓Answer: (A) Springer Nature

Springer Nature integrates Open Access through platforms like BioMed Central (BMC), which publishes fully OA journals where all articles are freely accessible under the Gold Open Access model.

12 April 2026

Which of the following best describes APC (Article Processing Charge)?

AFee paid by authors to publish OA

BFee for accessing articles

CFee for indexing journals

DFee for peer review

✓Answer: (A) Fee paid by authors to publish OA

APCs fund Gold OA publishing models.

11 April 2026

Journal “flipping” refers to:

AConverting OA journals into subscription journals

BChanging editorial boards

CTransitioning from subscription to full OA

DSwitching indexing databases

✓Answer: (D) Transitioning from subscription to full OA

Flipping is a key strategy in OA transformation.

10 April 2026

Which publisher is considered a pioneer of the modern Open Access movement?

AWiley

BSAGE Publications

CElsevier

DPublic Library of Science (PLOS)

✓Answer: (D) Public Library of Science (PLOS)

PLOS played a foundational role in establishing fully OA publishing ecosystems, especially with PLOS ONE.

09 April 2026

“Transformative agreements” primarily aim to:

AReplace peer review with open review

BConvert subscription costs into OA publishing support

CEliminate APCs completely

DRestrict access to institutional users

✓Answer: (B) Convert subscription costs into OA publishing support

These agreements shift institutional payments from reading (subscriptions) to publishing (OA funding).

08 April 2026

Which publisher follows a fully Gold Open Access model across all its journals?

AElsevier

BSpringer Nature

CMDPI

DTaylor & Francis

✓Answer: (C) MDPI

MDPI operates entirely under the Gold OA model, where all articles are immediately accessible upon publication.

07 April 2026

What is the primary function of tokenization in LLM pipelines?

AConverting text into units that can be numerically encoded

BEncrypting text data

CCompressing datasets

DRemoving stopwords

✓Answer: (A) Converting text into units that can be numerically encoded

Tokenization prepares raw text for machine processing by breaking it into units that can be mapped to numbers.

06 April 2026

Which statement best defines a “token” in LLMs?

AA complete sentence processed by the model

BThe smallest unit of meaning always equal to a word

CThe smallest unit of meaning always equal to a word

DA unit of text that may represent words, subwords, or characters

✓Answer: (D) A unit of text that may represent words, subwords, or characters

A token is a flexible unit—it can be a word, part of a word, or even punctuation. It is later converted into numerical form for processing.

05 April 2026

What is the main goal of AI governance?

AImprove model speed

BRegulate and guide AI development and use

CReplace human decision-making

DIncrease data volume

✓Answer: (B) Regulate and guide AI development and use

AI governance includes policies, standards, and regulations to ensure ethical and safe AI deployment.

04 April 2026

What is the key risk of an echo chamber in AI-driven platforms?

AReinforcement of existing beliefs

BData leakage

CReduced computational efficiency

DIncreased transparency

✓Answer: (A) Reinforcement of existing beliefs

Echo chambers limit exposure to diverse viewpoints, reinforcing biases and potentially spreading misinformation.

03 April 2026

Zero-shot prompting is most effective when:

AThe task requires strict formatting

BThe task is novel and unseen

CThe task is simple and generalizable

DThe dataset is small

✓Answer: (C) The task is simple and generalizable

Zero-shot works best for common, well-understood tasks where the model can generalize easily.

02 April 2026

What is zero-shot prompting?

AA method where the model is trained on zero data

BA prompting technique without providing examples

CA technique using one example in the prompt

DA method requiring reinforcement learning

✓Answer: (B) A prompting technique without providing examples

Zero-shot prompting involves giving only instructions to the model without any sample examples.
