Answer:
D. reducing the number of required rocket missions and thereby reducing the long-run average cost of exploring the solar system.
Explanation:
As you can see in the question above, the use of a 3D printer by astronauts can reduce the number of rocket emissions to transport equipment, parts for the repair of stations, food, construction of space bases, among others. This would be a great economic advantage for the laboratories, because it would allow reducing the number of rocket missions (which are extremely expensive) needed and thus reducing the average long-term cost of exploring the solar system.
A 3D printer is capable of printing a large number of parts and equipment at once, with an exact amount of raw material for that. This reduces material costs, in addition to avoiding waste of raw material.

Answer:
Trading securities.
Explanation:
A bond can be defined as a debt or fixed investment security, in which a bondholder (creditor or investor) loans an amount of money to the bond issuer (government or corporations) for a specific period of time.
Generally, the bond issuer is expected to return the principal at maturity with an agreed upon interest to the bondholder, which is payable at fixed intervals.
The par value of a bond is its face value and it comprises of its total dollar amount as well as its maturity value. Also, the par value of a bond gives the basis on which periodic interest is paid. Thus, a bond is issued at par value when the market rate of interest is the same as the contract rate of interest. This simply means that, a bond would be issued at par (face) value when the bond's stated rated is significantly equal to the effective or market interest rate on the specific date it was issued.
In Economics, bonds could either be issued at discount or premium.
Hence, a bond that is being issued at a discount has its stated rate lower than the market interest rate, on the specific date of issuance. Also, a bond that is being issued at a premium, has its stated rate higher than the market interest rate on the specific date of issuance.
Bonds that are purchased with the intent of selling them in the near future to take advantage of short-term price changes are classified as trading securities. Thus, trading securities such as debts or an equity are not held by business firms for a long-term period because they are purchased for the purpose of earning profits in a short-term period.
