Question

water: a cool molecule
teen channel: science scene
while walking to school one morning, you observe sparkling dewdrops on a spiderweb and stop to marvel at their shape, becoming completely absorbed in their scintillations... until you notice drops of water from the sky splashing on your head, sending you scurrying for shelter. since water is all around us, you might not spend much time contemplating why it acts the way it does, but water has many fascinating properties.
the shape of water molecules helps water drops form.
question 1
the article primarily discusses ______.
a. how ice floats in liquid water because of a difference in density
b. how all water molecules are made up of both hydrogen and oxygen atoms
c. how some insects can walk on water because of surface tension
d. how some properties of water are determined by the shape of the molecule

Explanation:

The article's title is "Water: A Cool Molecule" and the image caption mentions "The shape of water molecules helps water drops form". Option D states how some properties of water are determined by the shape of the molecule, which aligns with the title and the caption's hint. Options A, B, and C focus on specific properties (density, molecular composition, surface tension) rather than the overarching idea of molecular shape determining properties.

Answer:

D. how some properties of water are determined by the shape of the molecule
