CISA QUESTION #1726

Question 2643

Which of the following most accurately describes the structure of a continuing annual audit programme for regulatory compliance?

One comprehensive audit is conducted annually and its findings are reused in subsequent years.
The audit programme can be fully automated using dedicated audit management software.
A compliance audit programme consists of a series of distinct, time-limited projects that collectively address all annual compliance requirements.✔️
An annual audit consists of a series of assessments carried out by the auditee for licensing and regulatory purposes.

Correct Answer Logic:

An ongoing audit programme is not a single monolithic event — it is composed of multiple discrete projects, each with a defined start and end date, that together fulfil the full set of annual compliance requirements. These projects are unique and of limited duration, but may be coupled into a series to address an ongoing operational or regulatory need. This structure reflects sound project management principles applied to audit planning.

Civil / Architecture QUESTION #2364

Question 2644

In soil compaction, the Zero Air Voids (ZAV) curve or 100% saturation curve represents:

The maximum dry density achievable for a given soil at any compactive effort
The theoretical maximum dry density $\gamma_{d,max}$ at a given water content $w$ if all air voids are eliminated, given by $\gamma_d = \dfrac{G_s \gamma_w}{1 + w G_s}$✔️
The field density achieved by standard Proctor compaction test
The relationship between void ratio and effective stress during consolidation

Correct Answer Logic:

The ZAV curve is the theoretical upper bound of dry density at any moisture content, computed as $\gamma_d = \dfrac{G_s \gamma_w}{1 + w G_s}$, assuming $S = 100\%$ (all voids filled with water, no air). In practice, compaction curves plot below and to the left of the ZAV curve. The ZAV curve does not represent an achievable state during compaction but serves as a reference limit.

Biology Zoology Botany QUESTION #1359

Question 2647

Plants that grow under direct sunlight are known as:

Heliophytes✔️
Sciophytes
Psamophytes
Dicots

Correct Answer Logic:

Heliophytes (sun plants) are plants adapted to grow in full, direct sunlight. They have structural adaptations such as smaller, thicker leaves with more palisade mesophyll layers and higher chlorophyll content to optimise photosynthesis in high-light conditions. Sciophytes are shade-tolerant plants; psamophytes grow in sandy soil environments.

Tourism & Hospitality Management QUESTION #1637

Question 2649

The Tourism Marketing course discusses 'strategic alliances in the world airline industry' as referenced in the recommended readings. In the context of tourism marketing, such alliances primarily benefit tourists by offering which advantage?

Higher ticket prices through reduced competition
Seamless connectivity, code-sharing, reciprocal frequent flyer benefits, and expanded route networks that reduce the complexity and cost of international travel✔️
Exclusive access to first-class lounges only for alliance members
Standardized in-flight meal services across all alliance airlines

Correct Answer Logic:

Strategic alliances (such as Star Alliance, Oneworld, and SkyTeam) are referenced in the Tourism Marketing course's recommended readings (Bennett, 1997). For tourists, alliances deliver seamless connectivity through code-sharing, integrated booking, reciprocal frequent flyer benefits, and expanded global route networks — reducing layovers and improving the overall travel experience.

Agronomy QUESTION #2015

Question 2652

Agronomy is best defined as the branch of agricultural science that deals with:

The breeding and genetics of field crops only
The theory and practice of field crop production and soil management in relation to crop improvement✔️
The study of horticultural crops and their post-harvest management
The classification and taxonomy of cultivated plants

Correct Answer Logic:

Agronomy integrates both crop science and soil science to study the theory and practice of producing field crops. It encompasses soil management, tillage, nutrient management, irrigation, and crop protection — all aimed at maximizing yield and land use efficiency.

Question 2653

Two microbes found to be very useful in genetic engineering are:

Diplococcus sp. and Pseudomonas sp.
Crown gall bacterium and Caenorhabditis elegans
Escherichia coli and Agrobacterium tumefaciens✔️
Vibrio cholerae and a tailed bacteriophage

Correct Answer Logic:

E. coli is the workhorse of genetic engineering — used for cloning, protein expression, and plasmid propagation. Agrobacterium tumefaciens is used to introduce foreign genes into plant cells via its Ti plasmid. Together they are the most commonly used microbes in genetic engineering.

CISA QUESTION #1791

Question 2655

Which type of audit risk is represented by a failure to detect or prevent a material error from occurring?

Overall audit risk
Detection risk✔️
Inherent risk
Control risk

Correct Answer Logic:

Detection risk is the risk that the auditor fails to identify a material error that exists. It arises from limitations in the audit procedures used rather than from the nature of the subject matter. Proper sampling methods and thorough testing procedures are employed specifically to minimize detection risk.

Reading and Writing (Module-1) QUESTION #5356

Question 2658

Literary theorists often separate 'fabula' (story content) from 'syuzhet' (how the story is told). For instance, in The Godfather Part II, the fabula is the Corleone family history, while the syuzhet is the back-and-forth timeline structure. However, Mikhail Bakhtin argued these two terms aren't enough to describe a narrative, as they ignore the complex meaning created between the artist, the work, and the viewers. Which choice best states the main idea of the text?

Literary theorist Mikhail Bakhtin argued that there are important characteristics of narratives that are not fully encompassed by two concepts that other theorists have used to analyze narratives.✔️
Literary theorist Mikhail Bakhtin claimed that meaning is not inherent in a narrative but is created when an audience encounters a narrative so that narratives are interpreted differently by different people.
The storytelling methods used in The Godfather Part II may seem unusually complicated, but they can be easily understood when two concepts from literary theory are utilized.
Narratives that are told out of chronological order are more difficult for audiences to understand than are narratives presented chronologically.

Correct Answer Logic:

The main point is Bakhtin's critique that the existing concepts of fabula and syuzhet are 'insufficient' to describe narratives fully.

Chemistry QUESTION #5581

Question 2660

In the reaction sequence $CH_3COOH \xrightarrow{LiAlH_4} A \xrightarrow{PCl_5} B \xrightarrow{Alc.\ KOH} C$, the product C is:

Ethylene ($CH_2=CH_2$)✔️
Acetyl chloride ($CH_3COCl$)
Acetaldehyde ($CH_3CHO$)
Acetylene ($HC\equiv CH$)

Correct Answer Logic:

Step 1: $CH_3COOH \xrightarrow{LiAlH_4} CH_3CH_2OH$ (ethanol, A). Step 2: $CH_3CH_2OH \xrightarrow{PCl_5} CH_3CH_2Cl$ (chloroethane, B). Step 3: $CH_3CH_2Cl \xrightarrow{Alc.\ KOH} CH_2=CH_2$ (ethylene/ethene, C) by elimination. The final product C is ethylene.
