Practice Questions

Q1. Match List I with List II: 1. Rakesh Sharma 2. Kalpana Chawla 3. Sunita Williams. a. first woman of Indian origin to visit space b. first Indian citizen in space c. NASA astronaut selected in 1998.

A 1-a, 2-b, 3-c
B 1-c, 2-a, 3-b
C 1-b, 2-c, 3-a
D 1-b, 2-a, 3-c Correct

Explanation

The correct match is Rakesh Sharma as the first Indian citizen in space, Kalpana Chawla as the first woman of Indian origin to visit space, and Sunita Williams as the NASA astronaut selected in 1998. Mary can use this card sort without turning it into a long biography lesson.

Q2. A REET answer links sky observation in Class 3 with NEP 2020. Which link is most appropriate?

A NEP 2020 supports activity-based movement from foundational learning into preparatory EVS Correct
B NEP 2020 requires Class 3 children to calculate orbital speed
C NEP 2020 says astronomy must replace EVS integration
D NEP 2020 is irrelevant for Level 1 teaching decisions

Explanation

The NEP link should remain pedagogical. Class 3 sky observation grows from play and observation toward preparatory EVS concepts. It does not mean orbital calculations or dropping EVS integration. Asha’s shadow work fits the policy frame better.

Q3. Which is the safest syllabus boundary for teaching this topic in REET Level 1 EVS?

A Primary EVS links: light, weather, water cycle, Earth observation and simple space personalities Correct
B Detailed rocket engineering and orbital mechanics for all planets
C Only biographies of astronauts, without Earth or classroom observation
D Only memorising all planet sizes and distances in kilometres

Explanation

The RBSE anchor does not literally name the topic, so the best REET answer stays with EVS links: light, weather, water cycle, Earth observation and simple verified space personalities. Asha’s shadow diary is a better Level 1 method than a lecture on rocket engineering.

Q4. Which statement is best about textbook titles while preparing this topic?

A Use Looking Around as the current Class III EVS title
B Avoid all NCERT titles because EVS has no textbook links
C Use Our Wondrous World as current Class III EVS, and frame Looking Around historically Correct
D Use only NASA pages and never mention school textbooks

Explanation

Karan should not cite a legacy title as if it is current. The verified catalogue gives Our Wondrous World for Class III EVS in the NEP-2020 list, while older Looking Around material may be mentioned only as a historical classroom reference.

Q5. Which set contains only correctly paired ideas for REET Level 1?

A Rotation - year; Revolution - day and night; Rakesh Sharma - 2003
B Earth - third planet; Rotation - day and night; Rakesh Sharma - 3 April 1984 Correct
C Pluto - ninth main planet; Moon phases - Earth shadow every night; Sunita Williams - first Indian citizen
D Earth - first planet; Moon - star; Kalpana Chawla - flew Soyuz T-11

Explanation

The correct set is compact and classroom-ready: Earth is third from the Sun, rotation explains day and night, and Rakesh Sharma’s verified flight date is 3 April 1984. Karan can use this as a quick revision card.
