दिए गए विकल्पों में सही उत्तर विकल्प 3 ‘देशाटन’ है। अन्य विकल्प इसके अनुचित उत्तर हैं।

Key Points

• देशाटन का अर्थ होता है:- देश भ्रमण, पर्यटन करना।
• देशाटन का समास विग्रह:-
  • देश में अटन (भ्रमण)।
• अतः देशाटन शब्द तत्पुरुष समास का उदहारण है। क्योंकि यहाँ “का“ विभक्ति का लोप हुआ है। अतः सही उत्तर देशाटन होगा ।

अन्य विकल्प:-

Additional Information

• समास का तात्पर्य है ‘संक्षिप्तीकरण’। हिन्दी व्याकरण में समास का शाब्दिक अर्थ होता है छोटा रूप; जब दो या दो से अधिक शब्दों से मिलकर जो नया और छोटा शब्द बनता है उस शब्द को हिन्दी में समास कहते हैं।
• समास के उदाहरण:-
  • रसोई के लिए घर इसे हम रसोईघर भी कह सकते हैं।
  • राजा का पुत्र’ – राजपुत्र
• समास के निम्नलिखित छह भेद होते हैं—
• अव्ययीभाव समास - यदि एक शब्द की पुनरावृत्ति हो और दोनों शब्द मिलकर अव्यय की तरह प्रयोग हों वहाँ पर अव्ययीभाव समास होता है संस्कृत में उपसर्ग युक्त पद भी अव्ययीभाव समास ही मने जाते हैं।
• उदाहरण:-
  • प्रतिवर्ष =हर वर्ष
  • आजन्म = जन्म से लेकर
• तत्पुरुष समास - इस समास में दूसरा पद प्रधान होता है। यह कारक से जुदा समास होता है। इसमें ज्ञातव्य – विग्रह में जो कारक प्रकट होता है उसी कारक वाला वो समास होता है। इसे बनाने में दो पदों के बीच कारक चिन्हों का लोप हो जाता है उसे तत्पुरुष समास कहते हैं।
• उदाहरण:-
  • देश के लिए भक्ति = देशभक्ति
  • राजा का महल = राजमहल
• कर्मधारय समास - इस समास का उत्तर पद प्रधान होता है। इस समास में विशेषण -विशेष्य और उपमेय -उपमान से मिलकर बनते हैं उसे कर्मधारय समास कहते हैं।

  • महात्मा =महान है जो आत्मा
• द्विगु समास - द्विगु समास में पूर्वपद संख्यावाचक होता है और कभी-कभी उत्तरपद भी संख्यावाचक होता हुआ देखा जा सकता है। इस समास में प्रयुक्त संख्या किसी समूह को दर्शाती है किसी अर्थ को नहीं |इससे समूह और समाहार का बोध होता है। उसे द्विगु समास कहते हैं।
• उदाहरण:-
  • नवग्रह = नौ ग्रहों का समूह
  • दोपहर = दो पहरों का समाहार
• द्वन्द समास - इस समास में दोनों पद ही प्रधान होते हैं इसमें किसी भी पद का गौण नहीं होता है। ये दोनों पद एक-दूसरे पद के विलोम होते हैं लेकिन ये हमेशा नहीं होता है। इसका विग्रह करने पर और, अथवा, या, एवं का प्रयोग होता है उसे द्वंद्व समास कहते हैं।
• उदाहरण:-
  • जलवायु = जल और वायु
  • अपना-पराया = अपना या पराया
• बहुव्रीहि समास - इस समास में कोई भी पद प्रधान नहीं होता। जब दो पद मिलकर तीसरा पद बनाते हैं तब वह तीसरा पद प्रधान होता है। इसका विग्रह करने पर “वाला है, जो, जिसका, जिसकी, जिसके, वह” आदि आते हैं वह बहुब्रीहि समास कहलाता है।
• उदाहरण:-
  • गजानन = गज का आनन है जिसका (गणेश)

Important Points

The National Council for Teacher Education as a statutory body came into existence in pursuance of the National Council for Teacher Education Act, 1993 on the 17th August,1995.

Key Points

• NCTE is a policy designed to achieve planned and coordinated development of the teacher education system.
• NCTE mainly designs 'Teacher Education Program' or 'Teacher Training Programme which emphasizes upon:
  • developing self-confidence in the teacher.
  • developing a proper attitude towards teaching.
  • equipping teachers with innovative pedagogic skills.
  • understanding of major principles of child psychology.
  • enabling the teacher to understand the significance of individual differences.

Hence, it is clear that the policies for the development of the teacher education system are designed by the National Council for Teacher Education.

Additional Information

The meaning of "progressive education" depends on the meaning assigned to the word 'progress'. Progress implies movement and movement involves changes in some direction. 

• 'progressive education', is that body of educational thought that nourished in the fertile mind of John Dewey. 
• According to John Dewey, “Education is reconstruction or reorganisation of experience which adds to the meaning of experience and which increases the ability to direct the course of subsequent experiences.”

Key Points

• The assessment usually measures how much content (concepts and skill) has been achieved by a child out of the identified content he/she was supposed to achieve in a particular class. 
• Assessment plays a crucial role in enhancing the quality of teaching and learning for elementary students as it gives insight into children’s understanding and helps the teacher to reflects on her pedagogy. 
• The assessment provides learners feedback on his/her performance during classroom instruction, in unit tests, termed test, etc.
• Feedback helps learners to know about their strengths and weaknesses. Accordingly, a teacher can provide remedial inputs and learners can improve their learning. 

Thus from above-mentioned points, it is clear that in a progressive classroom, assessment of’ learners during the process of teaching-learning gives insights into children’s understanding and helps the teacher to reflects on her pedagogy. 

Integrated Child Development Services (ICDS) Scheme: The scheme was launched on 2nd October 1975.

• Home or community-based counselling may not benefit the child who has such problems in the school setting. 
• A common characteristic of Community-based counselling is that the professional develop close and personal bonds with his client.
• The counsellor needs to be professionally qualified and well-informed in his field and to understand how his work fits in with the work of others in the caring team; importantly, the counsellor should also be aware of how the physical,
  emotional, social and spiritual distress of his patients or clients influences him on a personal level as well as in discharging his professional responsibilities.

• School-based counselling fosters an environment that encourages students to develop self-awareness, as well as understanding, tolerance and acceptance of others’ diverse qualities, backgrounds, beliefs and aptitudes.

The variability of oxidation state, a characteristic of transition element arises due to incomplete filling of d-orbitals.

Carbon has 4 electron in its outermost shell. So it is difficult to loose electrons or gain electrons. That's why carbon forms covalent bond by sharing of electrons.

Cimetidine,zantac and ranitidine are antacids as they control the root cause of acidity These drugs prevent the interaction of histamine with the receptors present in the stomach walls Consequently there is a decrease in the amount of acid release by the stomach 

Correct Answer :- D

Explanation :

CO₂ and BeH₂ possess linear geometry as well as linear shape , while H₂O possess traversal geometry and bent shape.NF₃ possess traversal geometry and trigonal pyramidal shape . Thus correct option is (c)

Since, ΔG ° < 0, hence it is spontaneous in forward direction . Oxidation number of Xe decreases hence, it is an oxidising agent and oxidation number of F increases, hence it is a reducing agent.

Lactose: The sugar found naturally in milk, it is a disaccharide composed of one galactose unit and one glucose unit; sometimes called milk sugar.

H-bonding is between polar and electronegative 0, N and F C-atom or H attached to C is not polar. Thus, (a), (c), (d) are incorrect.

For second order reaction half life is inversely related to concentration of reactant.

The correct answer is option B
Given,
λCo(NH3)4Cl2+=50       λClo-4 =70
λ∞= λCo(NH3)4Cl2+  + λClo-4
λ∞= 50             + 70
λ∞=120
(x) Cell constant = 1/A
0.02 = l/A
Resistance(R)   =33.5Ω
K =c.x              (x = is cell constant)

S  =49.7 mol/L

Cl, O, and N forms Cl₂, O₂ and N₂ respectively to satisfy octet rule but He has noble gas configuration so do not form any compound and exist as monoatomic gas.

By Fajans’ rule, smaller the size of cation, larger the size of anion, larger the charge on cation or anion,
d- and f-electrons present on the ion then greater the polarising power of the ion to polarise the other ion, thus larger the covalent nature.

Thus, com pound with Si⁴+ (smallest cation) and C^4- (largest anion) will be most covalent.
