Answer 1

"As Malar’s mother accidentally mixed groundnuts with urad-dhal, she can hand pick the ground nuts so that Malar can eat them separately.

As groundnuts are bigger in size, it can easily be handpicked.

The glass of water containing tamarind juice and sugar is a mixture as they can be separated.

The taste will be sweet or sour depending upon the proportion of sugar or tamarind juice mixed.

The third part is vague. "

Answer 2

"चूंकि मालार की मां दुर्घटनाग्रस्त मूत्रफली उरद-ढल के साथ मिश्रित होती है, इसलिए वह जमीन के नटों को चुन सकती है ताकि मालार उन्हें अलग से खा सके।

चूंकि मूंगफली आकार में बड़ी हैं, इसे आसानी से हाथ से बनाया जा सकता है।

चिमनी के रस और चीनी युक्त पानी का गिलास एक मिश्रण है क्योंकि उन्हें अलग किया जा सकता है।

चीनी या चिमनी के रस के अनुपात के आधार पर स्वाद मीठा या खट्टा होगा।

तीसरा हिस्सा अस्पष्ट है। "
