Statement:\nOlder women using assisted reproductive technology are usually monitored more closely and are more likely to receive counselling and prenatal tests. They also tend to be more affluent and educated and avoid risky behaviours when approaching pregnancy.\nConclusions:\nI. Health risks to children born to women above 35 are not significantly greater.\nII. Twins and triplets born to older women are just as healthy as those born to younger mothers.

Introduction / Context:
The statement lists process and behaviour differences for older mothers: more medical monitoring, more testing, greater affluence/education, and more caution. We must determine whether specific outcome claims about risks and health necessarily follow from those inputs.

Given Data / Assumptions:

• Older women using ART receive closer surveillance and counselling.
• They may be more affluent/educated and avoid risky behaviours.
• No quantitative outcome data (risk rates, morbidity, mortality) are presented.

Concept / Approach:
More monitoring and cautious behaviour do not by themselves prove that health risks are “not significantly greater.” That requires comparative outcomes with younger mothers, which the statement lacks. Likewise, saying twins/triplets to older mothers are “just as healthy” as to younger mothers requires direct health outcome evidence for multiples across age groups; the statement only comments on management and behaviours, not outcomes.

Step-by-Step Solution:
1) Conclusion I makes a strong comparative outcome claim absent in the premise → does not follow.2) Conclusion II also makes a specific equivalence claim about multiples across ages → not supported by any provided statistics or assertions.

Verification / Alternative check:
If the statement had said “data show equal risk,” I and/or II could follow. As written, it stops at monitoring, counselling, and behaviour differences.

Why Other Options Are Wrong:
Only I/Only II/Either: each elevates management factors into guaranteed results without evidence.

Common Pitfalls:
Assuming that better monitoring/counselling nullifies age-related risks; conflating inputs (care processes) with outputs (health outcomes).

Final Answer:
if neither I nor II follows
