Introduction to ICT and its role in daily life

Correct answer: D. Transparency and accountability

Explanation: The governing concept is accountable digital service delivery. A platform that only receives a complaint creates a record, but progress tracking lets the complainant see whether the issue was assigned, investigated, or resolved. Without that visibility, transparency is reduced and officials are less answerable for follow-up. Entertainment, compression, and image editing are unrelated functions. Therefore, option D is correct.

Correct answer: A. People speaking different languages can understand essential information

Explanation: The governing concept is ICT improving communication and access. A translation tool has the greatest social value when it helps people who speak different languages understand essential information such as health, safety, education, or public services. It can reduce a language barrier, although important translations should be reviewed by a knowledgeable person. The other choices involve careless, deceptive, or trivial use. Thus option A is correct.

Correct answer: D. It may incorrectly change a correct word or number

Explanation: The governing concept is the limitation of automated processing and the need for contextual verification. An autocorrection feature uses programmed rules or patterns, so it may misunderstand a name, technical term, address, or numerical entry and replace a correct value with an incorrect one. It does not stop storage or control screen brightness. Because human review can catch such context errors, option D is correct.

Correct answer: C. A technical failure marks present students as absent

Explanation: The governing concept is data quality and fairness in decision-making. A digital record is useful only when it accurately represents the real event. If a technical failure marks students absent even though they attended, the record conflicts with reality and cannot fairly support punishment or other decisions until it is checked against evidence such as teacher confirmation. Thus option C is correct; the other situations strengthen reliability rather than weaken it.

Correct answer: D. Check the need for permissions and deny unnecessary permissions

Explanation: The governing concept is least privilege: an application should receive only the access needed for its stated function. Excess permissions can expose contacts, location, files, camera or microphone data and increase privacy and security risks. Option D applies the correct process—check the purpose, review the app and deny access that is not justified. Granting everything, sharing a password or deleting a review does not control the risk.

Correct answer: A. Secure copies of an important document are stored in separate locations

Explanation: The governing concept is reliable digital storage through backup and availability planning. Keeping secure copies in separate locations preserves information if one device, account or site is damaged, lost or attacked, while a usable copy remains available when needed. Therefore option A supports both preservation and availability. A single unbacked file can be lost, a public password weakens security, and unnamed records make retrieval and accountability difficult.

Correct answer: B. Text, activities, feedback and support may also be needed for different learning needs

Explanation: The governing concept is inclusive and effective digital learning. Videos can explain ideas, but learning also requires opportunities to read, practise, ask questions, receive feedback and obtain support. Different learners may have different access needs, learning speeds or preferences, so a varied resource design is stronger. Option B is correct. Options A and C make absolute claims, while D is technically false because online videos generally require connectivity or prior download.

Correct answer: C. Excessive data retention and privacy risk

Explanation: The governing concept is responsible ICT use, especially purpose limitation, data minimisation, and privacy. Identifiable images should be collected only for a clear need and retained only as long as necessary. Keeping them for an excessive period increases the chance of misuse, unauthorised access, or surveillance. Therefore, option C is correct; the camera colour, road length, and signal height do not address the data-protection concern.

Correct answer: D. When a complex issue is shown as a single number without context

Explanation: The governing concept is data interpretation: an output must be understood with its source, context, method, and limitations. A single number can hide differences, uncertainty, missing information, or important causes, so it may lead to an incorrect conclusion when used alone. Option D is correct because it describes loss of context. The other situations improve reliability rather than create misleading interpretation.

Correct answer: B. When the review is extremely general and gives no usage details

Explanation: The governing concept is evaluating digital information and evidence. A useful review normally gives specific details about use, time, conditions, advantages, and problems. A very general statement with no usage evidence cannot show whether the product actually met the reviewer’s needs, so option B is correct. Verified repeated experiences, balanced comments, and comparisons across sources provide stronger evidence for a decision.

Correct answer: C. Authorised doctors can view tests, medicines, and treatment history in one consistent record

Explanation: The governing concept is integrated ICT for continuity, efficiency, and secure service delivery. When authorised doctors can view a consistent history of tests, medicines, and treatment, they can avoid unnecessary repetition and make better-informed decisions. Option C is correct. Separate identities and repeated information reduce coordination, while making every record public violates confidentiality and is not a benefit of integration.

Correct answer: D. It may increase inequality by excluding users with lower technical skills

Explanation: The governing concept is digital inclusion and the social impact of ICT. If a platform requires advanced technical skills, people with limited digital literacy, less experience, or fewer learning opportunities may be unable to use its services. This digital exclusion can widen existing inequality, so option D is correct. Equal opportunity requires accessible design, clear guidance, and support; the other options ignore the participation barrier.

Correct answer: A. A school analyses digital data and sends devices to classes that have fewer of them

Explanation: The governing concept is using ICT and current information to support fair, need-based decisions. Analysing digital records helps the school identify which classes have the greatest shortage, so directing devices there uses limited resources where they are most needed. Option A is correct. Keeping all devices in one room, relying on old estimates, or distributing equally without checking need may ignore current shortages and waste resources.

Correct answer: A. When responses are collected only from people with internet access and other groups are excluded

Explanation: The governing concept is sampling or selection bias. If a digital survey includes only people who have internet access, people without devices, connectivity, or digital skills are excluded. Their views may differ, so the sample cannot fairly represent the whole population. Therefore, option A is correct. Equal opportunity, clear questions, and secure recording improve survey quality but do not themselves create this bias.

Correct answer: B. When it offers search and resizing but some students lack devices

Explanation: The governing concept is the digital divide. Search, zoom, and text-resizing make an e-book useful and adaptable, but students without a suitable device, electricity, or connection may be unable to use it. Thus option B correctly combines greater functionality with reduced access. Option A removes the access problem, while C and D do not describe a useful e-book.

Correct answer: C. Changing text size and audio options according to visual needs

Explanation: The governing concept is personalisation and accessible design. An ICT system that changes text size or provides audio according to a person’s visual needs presents information in a suitable form. Therefore, option C is correct. Giving everyone identical settings ignores individual differences, deleting settings removes adaptation, and disabling options reduces access rather than improving it.

Correct answer: D. Have the translation verified by an expert and compare it with the original

Explanation: The governing concept is responsible use of ICT according to risk. Legal information can affect rights and duties, so an automatic translation must be checked by a qualified human and compared with the original wording. Option D is correct. Accepting it blindly risks harm, deleting the source removes evidence, and stopping every translation service is unnecessary and impractical.

Correct answer: A. When user numbers are high but incorrect outcomes and complaints are also high

Explanation: The governing concept is evaluating ICT by quality, safety, accessibility, and outcomes rather than popularity alone. A service may attract many users while producing errors and complaints, so high usage does not prove success. Option A therefore requires broader measurement. Options B and C already describe positive quality evidence, while D describes a process, not a warning situation.

Correct answer: D. When the content is incorrect and no feedback or support is available

Explanation: The governing concept is that technology enables access but does not replace teaching quality. Fast internet can deliver a lesson quickly, yet incorrect content, no feedback, and no learner support prevent meaningful learning. Option D is correct. Clear teaching, syllabus-aligned material, and opportunities to ask questions are supportive conditions, not failures of online education.

Correct answer: A. Checking the issuer and validity of a certificate through a digital verification feature

Explanation: The governing concept is authenticity checking through reliable evidence. A digital verification feature can connect a certificate with its issuer and show whether its record is valid, so option A is correct. Colour is only appearance, a screenshot can be copied or altered, and an unknown message has no confirmed source. Verification requires checking origin and validity, not merely trusting what is displayed.

Correct answer: B. People with low digital literacy or limited devices

Explanation: The governing concept is inclusion during digital transformation. People with limited digital literacy, poor connectivity, disabilities, or few devices may depend on human help or an alternative offline route. Closing the help centre can therefore affect option B most. Skilled users may manage independently, programmers are not the main service users, and online sellers are only one possible group.

Correct answer: C. An item is sold but the record is not updated

Explanation: The governing concept is data accuracy: a digital inventory is only reliable when every physical movement is recorded correctly and promptly. If an item is sold but the database is not updated, the system may show one extra item even though none is available. Immediate recording, correct codes, and physical checks reduce this error; therefore, option C identifies the actual cause.

Correct answer: D. When the system shows only options similar to past behaviour and hides new opportunities

Explanation: The governing idea is that ICT should support informed choice, not restrict it. Personalised systems can become limiting when they repeatedly use past behaviour to display only familiar options, because the user may not discover new information, products, or viewpoints. The other choices preserve choice or transparency, so option D is the only example of a harmful filter effect.

Correct answer: A. A traveller checks real-time status and official updates before changing the plan

Explanation: ICT reduces uncertainty when it provides timely, relevant, and trustworthy information for a decision. Checking a transport service’s real-time status and official updates allows a traveller to revise the route or schedule using current evidence. Old messages, unchecked tickets, and rumours may increase uncertainty, so option A is the only choice showing effective ICT use.

Correct answer: B. To avoid sending an incorrect or confidential file to the wrong person

Explanation: The governing concept is responsible digital communication. Verifying the recipient prevents a message or confidential attachment from reaching the wrong person, while checking the file prevents an outdated, incorrect, or unintended document from being shared. This reduces communication errors and privacy risks. Message length, internet speed, and file colour are unrelated, so option B is correct.
