Question

logan read about snail shells in his science book. which new idea can logan form now that he has read the text and seen the photograph? snails make their shells by releasing a liquid that hardens and forms a protective covering. more liquid is
snail shells are made from liquid, which might dissolve in wet weather.
predators do not like spiral - shaped objects.
snail shells do not change over time.
snails make their own shells over time, which is why they have a circular or spiral shape.

Explanation:

The text states that snails make their shells by releasing a liquid that hardens. The photograph shows a snail shell. The idea that snails make their own shells over time (as they release more liquid which hardens) connects the text (about the liquid - shell formation process) and the visual (the shell itself). Other options:

• "Snail shells do not change over time" - contradicts the text's implication of a process (releasing more liquid, so change occurs).
• "Predators do not like spiral - shaped objects" - no mention of predators in text or visual relevance.
• "Dissolve in wet weather" - no text support.
• "Circular or spiral shape" - while true, the key connection is the shell - making process (snails making their own shells over time) which is a new idea formed from text (liquid release) and photo (shell existence).

Answer:

Snails make their own shells over time.
