357: Consider the following statements:
1. A widely used musical scale called diatonic scale has seven frequencies.
2. The frequency of the note Sa- (lk) is 256 Hz and that of Ni- (uh) is 512 Hz.
Which of the statements given above is/are correct ?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation:
In music theory, a diatonic scale is a seven-note musical scale comprising five whole-tone and two half-tone steps, in which the half-steps are maximally separated. Thus between each of the two half-steps lie either two or three wholesteps, with the pattern repeating at the octave.
The musicians read the notes, interpret them according to "Sa, Re, Ga, Ma..." or "Do, Re, Me...", etc. For Sa, the frequency is 256 Hz, similarly, for Re, it is 288 Hz and for Ga, it is 320 Hz and so on.
358: Two of the schemes launched by the Government of India for Women's development are Swadhar and Swayam Siddha. As regards the difference between them, consider the following statements:
1. Swayam Siddha is meant for those in difficult circumstances such as women survivors of natural disasters or terrorism, women prisoners released from jails, mentally challenged women etc. whereas Swadhar is meant for holistic empowerment of women through Self Help Groups.
2. Swayam Siddha is implemented through Local Self Government bodies or reputed Voluntary Organizations whereas Swadhar is implemented through the ICDS. units set up in the states.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation:
Swayamsidha (2000-01) is an integrated scheme for the development an empowerment of women both socially and economically through Self Help Groups to enable them live with dignity and self-reliance. The scheme lays stress on access to micro-credit and envisages block and panchayat-level participation among women, cutting across all regional, economic and social groups.
Swadhar : The Swadhar Scheme was launched in Department during the year 2001-02 as a Central Sector Scheme for providing holistic and integrated services to women in difficult circumstances such as destitute winds deserted by their family in religious places like Vrindaban and Kashi, women prisoners from jail and without family support. The scheme is implemented through PSUs, District Rural Development Agencies, Federations, Cooperatives and Voluntary Organisations - Non-governmental Voluntary Organisations working in rural areas with legal status as a society.

(a) Both A and R are individually true and R is the correct explanation of A
(b) Both A and R are individually true but R is not the correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
Explanation:
India's Natural Rubber Consumption and Production are 0.718 mt. and 0.711 mt. respectively which shows that India doesn't export-natural rubber. About 97% of India's demand of natural rubber is met from domestic production and rest 3% from imports.
360: Assertion (A):
A piece of copper and a piece of glass are heated to the same temperature. When touched, thereafter, the copper piece appears hotter than the glass piece.
Reason (R):
The density of copper is more than that of glass.
(a) Both A and R are individually true and R is the correct explanation of A
(b) Both A and R are individually true but R is NOT a correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
Explanation:
Copper has low specific heat capacity and high thermal conductivity compared to the glass. Hence copper piece appears hotter than the glass piece not because of density.
