Explanation:

Window lintels support the structure above windows. Missing lintels can cause air leakage, sagging openings, water leakage which can lead to mold and mildew. Condensation is mainly related to temperature - humidity differences, not directly to missing lintels. For water sources in homes, plumbing leaks, heating leaks, sewer back - up, and dripping faucets are common water sources, while siding leaks are more about exterior wall protection rather than typical water sources inside homes.

Answer:

Question 1: A. condensation
Question 2: C. siding leaks
