Question 1 of 5
1. Question
1 pointsWhich of the following services generally use encryption to secure data transmission?
- Payment gateways
- Messaging services
- Wireless intercom systems
- Bank automatic teller machines
Select the correct answer code:
Correct
Solution: d)
Encryption is the process of encoding messages or information in such a way that only authorized parties can read it.
All messaging services like WhatsApp, Viber, Google Chat, Yahoo messenger use encrypted services. Banks (payment gateways) and e-commerce sites also use encryption to protect financial and private data including passwords.
Encryption is also used to protect data in transit, for example data being transferred via networks (e.g. the Internet, e-commerce), mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices and bank automatic teller machines.

Question 2 of 5
2. Question
1 pointsConsider the following statements regarding Goldilocks zone.
- Goldilocks zone, is the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
- If a planet is in the Goldilocks Zone of a star, it necessarily means the planet is going to have life or liquid water.
Which of the above statements is/are correct?
Correct
Solution: a)
The Goldilocks Zone refers to the habitable zone around a star where the temperature is just right – not too hot and not too cold – for liquid water to exist on a planet.
Just because a planet or moon is in the Goldilocks Zone of a star, doesn’t mean it’s going to have life or even liquid water.
After all, Earth isn’t the only planet in the Sun’s Goldilocks Zone – Venus and Mars are also in this habitable zone, but aren’t currently habitable.

Question 3 of 5
3. Question
1 pointsConsider the following statements regarding Incremental Capital-Output Ratio (ICOR).
- The incremental capital output ratio (ICOR) denotes the relationship between the level of investment made in the economy and the consequent increase in the gross domestic product (GDP).
- The higher the ICOR, the higher will be the productivity of capital.
Which of the above statements is/are correct?
Correct
Solution: a)
The Incremental Capital-Output Ratio (ICOR) is the ratio of investment to growth which is equal to the reciprocal of the marginal product of capital. The higher the ICOR, the lower the productivity of capital or the marginal efficiency of capital. The ICOR can be thought of as a measure of the inefficiency with which capital is used.

Question 4 of 5
4. Question
1 pointsConsider the following statements.
- The accelerated Arctic warming changes the temperature contrast between mid and high latitudes.
- Arctic warming is always harmful for the whales.
Which of the above statements is/are incorrect?
Correct
Solution: b)
The Arctic is warming far more quickly.
While both the Arctic and Antarctic are experiencing rising temperatures, thinning glaciers, disturbed ecosystems, and other alarming shifts as heat-trapping fossil fuel emissions build up, changes are sweeping the northern region far faster.
The High North is seeing unprecedented changes, including drastic ice losses on land and sea, galloping permafrost thaw, raging wildfires, unseasonal storms, earlier springs, and more.
The accelerated Arctic warming impacts weather down in the lower 48 and around the entire Northern Hemisphere by changing the temperature contrast between mid and high latitudes.
Arctic warming also stands to disrupt the marine food web, increase mortality for polar bears and seals, and threaten the livelihoods of the region’s indigenous people. One bright note in the outlook: So far whales seem to be benefitting from range expansion as sea ice recedes.
