{ii} Their hanging nests help protect eggs and chicks from predators.

The correct answer is {a}.
Explanation
{i} Soldier ants are specialised members of the colony responsible for protecting the nest from enemies.
{ii} They possess strong jaws that help in defending the colony.
{iii} Worker ants mainly collect food and care for eggs and larvae, whereas the queen lays eggs.
Additional Information
{i} An ant colony generally consists of a queen, worker ants, soldier ants, and immature stages such as eggs, larvae, and pupae.

The correct answer is {d}.
Explanation
{i} Himachal Pradesh receives snowfall and heavy rainfall in many regions.
{ii} Slanting roofs prevent the accumulation of snow and rainwater.
{iii} Stone and wood are locally available building materials in the hilly regions.
{iv} Therefore, such houses are commonly found in Himachal Pradesh.
Additional Information
{i} In Rajasthan, houses generally have flat roofs due to the hot and dry climate, whereas in Assam houses are often built on stilts because of frequent floods.

The correct answer is {b}.
Explanation
{i} Kings often had their orders engraved on rocks, pillars, or copper plates so that people could read and follow them.
{ii} Separate inscriptions were also prepared to record the achievements, donations, victories, and important works of kings and queens.
{iii} Both statements are correct.
{iv} However, the existence of other inscriptions does not explain why royal orders were inscribed for public reading and obedience.
Additional Information
{i} The inscriptions of Emperor Ashoka are among the most famous examples of royal inscriptions found in India.

The correct answer is {a}.
Explanation
{i} Solar energy and tidal energy are renewable because they are continuously replenished by natural processes.
{ii} Non-renewable resources such as coal, petroleum, and natural gas require millions of years to form and cannot be replenished within a human lifetime.
{iii} Thus, the reason is essentially true in the sense that non-renewable resources regenerate over extremely long geological periods.
{iv} However, this does not explain why solar and tidal energy are renewable; their renewability is due to their continuous natural availability. Therefore, both statements are true, but the reason is not the correct explanation of the assertion.
Additional Information
{i} Renewable energy sources include solar, wind, hydropower, tidal, geothermal, and biomass energy. They help reduce dependence on fossil fuels and lower environmental pollution.

The correct answer is {b}.
Explanation
{i} The NCERT EVS theme "Travel" integrates concepts from history, architecture, mathematics, and environmental studies.
{ii} Activities involving historical buildings often require estimation, comparison, and measurement, thereby strengthening quantitative thinking.
{iii} These experiences prepare children for more advanced mathematical skills in later classes.
{iv} Therefore, developing estimation and measurement skills is the objective reflected in this activity.
Additional Information
{i} EVS themes are interdisciplinary and connect children's experiences with science, mathematics, social science, and language learning.

The correct answer is {a}.
Explanation
{i} EVS themes at the primary stage are selected according to children's immediate experiences and surroundings.
{ii} Cooking food and sharing meals with family are familiar experiences for most Class III children.
{iii} Learning therefore begins from situations that children can easily relate to.
Additional Information
{i} The NCERT EVS curriculum follows the principle of moving from the familiar to the unfamiliar.

The correct answer is {a}.
Explanation
{i} The purpose of including such stories is to help children understand how scientific knowledge develops through observation, investigation, experimentation, and perseverance.
{ii} It introduces learners to the scientific method rather than merely presenting facts.
{iii} Such narratives also develop appreciation for the efforts of scientists behind important discoveries.
{iv} Therefore, Option {a} best reflects the educational objective.
Additional Information
{i} EVS encourages learning science as a process of inquiry rather than memorisation of facts.

The correct answer is {b}.
Explanation
{i} The principle of moving from the concrete to the abstract means beginning with children's direct experiences before introducing abstract concepts.
{ii} Linking classroom learning with children's own life experiences best represents this principle.
{iii} Participation in knowledge construction is a constructivist principle but does not specifically indicate the concrete-to-abstract principle.
{iv} Therefore, only Statement {I} correctly represents the given principle.
Additional Information
{i} EVS teaching follows the principles of known to unknown, simple to complex, and concrete to abstract.

The correct answer is {a}.
Explanation
{i} The "Expression" area evaluates how children communicate their ideas using speech, writing, drawings, diagrams, or other creative forms.
{ii} Expressing ideas through pictures directly reflects this learning indicator.
{iii} Participation relates to classroom involvement, whereas hypothesising and prediction belong to process skills.
Additional Information
{i} NCERT EVS assessment encourages multiple modes of expression instead of relying only on written responses.

The correct answer is {b}.
Explanation
{i} A rubric clearly specifies the performance criteria and different levels of achievement for an activity or task.
{ii} It can be used to assess written work, oral presentations, projects, field visits, and other learning activities.
{iii} Rubrics provide transparent expectations and help ensure objective assessment.
{iv} Therefore, a rubric is the most appropriate assessment tool in the given situation.
Additional Information
{i} Rubrics support continuous and comprehensive assessment by providing clear performance descriptors.

The correct answer is {a}.
Explanation
{i} EVS promotes child-centered learning where children actively explore, observe, investigate, and construct knowledge.
{ii} It emphasizes the development of problem-solving abilities, critical thinking, values, and environmental sensitivity.
{iii} A teacher-centered approach limits children's active participation and inquiry.
{iv} Therefore, it is not the most appropriate approach for EVS learning.
Additional Information
{i} The National Curriculum Framework recommends experiential and child-centered pedagogy for EVS at the primary level.

The correct answer is {a}.
Explanation
{i} Process skills involve observing, analysing, discussing, experimenting, interpreting, and drawing conclusions.
{ii} Retrieving facts mainly assesses memory or recall rather than inquiry skills.
{iii} Therefore, retrieving facts is not considered a process skill.
Additional Information
{i} EVS places greater emphasis on process skills than on memorisation of information.

The correct answer is {c}.
Explanation
