Marine robotics engineers establishing operational parameters for deep-sea exploration submersibles documented the following protocols:

• Any exploration submersible deployed in the Mariana Abyssal Zone that is equipped with an acoustic doppler profiler also carries a high-resolution photogrammetry rig.
• No exploration submersible carrying a high-resolution photogrammetry rig operates without a redundant lithium-polymer power backup.
• Every exploration submersible that operates with a redundant lithium-polymer power backup is certified for deep-trench hydrothermal survey missions.
• Some exploration submersibles deployed in the Mariana Abyssal Zone that are equipped with an acoustic doppler profiler are not certified for autonomous benthic sediment coring.

If all the statements above are true, which of the following statements must also be true? (Select all that apply.)

  1. Any exploration submersible equipped with a high-resolution photogrammetry rig is certified for deep-trench hydrothermal survey missions.Cevap
  2. B
    Every exploration submersible certified for deep-trench hydrothermal survey missions carries a high-resolution photogrammetry rig.
  3. At least some exploration submersibles certified for deep-trench hydrothermal survey missions are not certified for autonomous benthic sediment coring.Cevap
  4. D
    No exploration submersible certified for autonomous benthic sediment coring operates with a redundant lithium-polymer power backup.
  5. E
    Any exploration submersible that operates with a redundant lithium-polymer power backup is deployed in the Mariana Abyssal Zone.

Cevap

The statements establishing that any submersible with a photogrammetry rig is certified for hydrothermal survey missions, and that some hydrothermal-certified submersibles are not certified for benthic sediment coring, are both logically guaranteed.
The deduction that every submersible equipped with a photogrammetry rig is certified for hydrothermal survey missions directly follows from connecting the second premise to the third premise in a two-step conditional chain. Furthermore, the deduction that at least some submersibles certified for hydrothermal survey missions are not certified for benthic coring follows from tracing the submersibles identified in the fourth premise through the conditional chain: they possess photogrammetry rigs, which guarantees power backups, which in turn guarantees hydrothermal certification, while simultaneously lacking sediment coring certification.

Adım Adım Çözüm

1
Diagram the conditional rules linking equipment and certifications.
Photogrammetry Rig → Lithium-Polymer Power Backup → Hydrothermal Survey Certified.
Chaining the second and third premises proves that having a photogrammetry rig guarantees hydrothermal survey certification.
2
Synthesize the existential premise with the conditional chain.
Some (Mariana & Acoustic Doppler) submersibles exist that are NOT Coring Certified. Since (Mariana & Acoustic Doppler) implies Photogrammetry Rig, Power Backup, and Hydrothermal Certification, these specific submersibles are Hydrothermal Certified but NOT Coring Certified.
An existential quantifier ('some') linked to the sufficient condition of a valid chain transfers all downstream necessary properties to those specific members.
3
Evaluate the answer choices against the deduced relationships.
Two statements strictly follow from the deductive chain, while the remaining choices commit formal conditional reversal, illicit negation, or scope overextension.
In Must Be True questions, only claims that are 100% logically necessitated by the premises are correct.
