Problem: Avicenna:

Avicenna's consideration of the essence-attributes question may be elucidated in terms of his ontological analysis of the modalities of being; namely impossibility, contingency, and necessity. Avicenna argued that the impossible being is that which cannot exist, while the contingent in itself (mumkin bi-dhatihi) has the potentiality to be or not to be without entailing a contradiction. When actualized, the contingent becomes a 'necessary existent due to what is other than itself' (wajib al-wujud bi-ghayrihi). Thus, contingency-in-itself is potential beingness that could eventually be actualized by an external cause other than itself. The metaphysical structures of necessity and contingency are different. Necessary being due to itself (wajib al-wujud bi-dhatihi) is true in itself, while the contingent being is 'false in itself' and 'true due to something else other than itself'. The necessary is the source of its own being without borrowed existence. It is what always exists.

According to Avicenna, what could eventually be actualized by an external cause?
---
A: contingency-in-itself

Problem: Endangered Species Act:

The "Safe Harbor" agreement is a voluntary agreement between the private landowner and FWS. The landowner agrees to alter the property to benefit or even attract a listed or proposed species in exchange for assurances that the FWS will permit future "takes" above a pre-determined level. The policy relies on the "enhancement of survival" provision of Section 1539(a)(1)(A). A landowner can have either a "Safe Harbor" agreement or an Incidental Take Permit, or both. The policy was developed by the Clinton Administration in 1999.

What two groups are bound by a "Safe Harbor" agreement?
---
A: the private landowner and FWS

Problem: Iran:

Other non-governmental estimations regarding the groups other than the Persians and Azerbaijanis roughly congruate with the World Factbook and the Library of Congress. However, many scholarly and organisational estimations regarding the number of these two groups differ significantly from the mentioned census. According to many of them, the number of ethnic Azerbaijanis in Iran comprises between 21.630% of the total population, with the majority holding it on 25%.cd In any case, the largest population of Azerbaijanis in the world live in Iran.

What is the percentage range of Iran's total population is seemingly comprised of Azerbaijanis?
---
A:
between 21.630%
