With reference tothe FASTag device, recently in news, consider the following statements:
1. It uses a stereo camera and LiDAR technology.
2. If a potential collision is detected, it first tries to alert the driver that an emergency is needed.
Which of the statements given above is/are correct?
• FASTag is a Radio Frequency Identification (RFID) passive tag used for making toll payments directly from the customers linked prepaid or savings/current account. It is affixed on the windscreen of the vehicle and enables the customer to drive through toll plazas, without stopping for any toll payments. The toll fare is directly deducted from the linked account of the customer.
• FASTag employs Radio Frequency Identification (RFID) technology for making toll payments directly while the vehicle is in motion. Hence, statement 1 is incorrect.
• Statement 2 is incorrect. FASTag is not equipped with any such technology which can alert the diver about any potential collision.
About Radio-Frequency Identification technology:
• Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked.
• An RFID system is made up of two parts: a tag or label and a reader. RFID tags or labels are embedded with a transmitter and a receiver. The RFID component on the tags has two parts: a microchip that stores and processes information, and an antenna to receive and transmit a signal.
• The tag contains the specific serial number for one specific object. To read the information encoded on a tag, a two-way radio transmitter-receiver called an interrogator or reader emits a signal to the tag using an antenna. The tag responds with the information written in its memory bank. The interrogator will then transmit the read results to an RFID computer program.
• There are two types of RFID tags: passive and battery-powered. A passive RFID tag will use the interrogator's radio wave energy to relay its stored information back to the interrogator. A battery-powered RFID tag is embedded with a small battery that powers the relay of information. FASTag is an example of a passive RFID device.

With reference to Active Pharmaceutical Ingredient (API), which of the following statements is/are correct?
1. These are the secondary ingredients that perform a crucial role in delivering a drug to our system.
2. Certain drugs are comprised of more than one kind of API.
Select the correct answer using the code given below:
• Statement 1 is incorrect. Active Pharmaceutical Ingredients are portions of any drug, which are active. All drugs are made up of two core components: the API, which is the central ingredient, and the excipient, the substance inside the drug that helps deliver the medication to your system. Excipients are chemically inactive substances, such as mineral oil.
• Active ingredients are those which are intended to have therapeutic and pharmacologic activity. So, it is the main portion of a drug product intended to produce a therapeutic effect. On the other hand, Inactive ingredients are added for formulation compatibility and proper drug delivery i.e. binding ingredients, disintegrants, flavors, color dyes etc.
• For instance, if you have a headache, acetaminophen is the active ingredient, while the liquid in the capsule or the bulk of a pill is the excipient. Statement 2 is correct. Certain drugs are comprised of more than one kind of API.

Regarding Flex-fuel cars, consider the following statements:
1. Flex-fuel cars are designed to run on more than one fuel.
2. They are also known as bi-fuel vehicles.
Which of the above statements is/are correct?
• Statement 1 is correct. A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.
• Statement 2 is incorrect. Flex-fuel vehicles are different from bi-fuel vehicles, where two fuels are stored in separate tanks and the engine runs on one fuel at a time, for example, compressed natural gas (CNG), liquefied petroleum gas (LPG), or hydrogen.

The project 'Meghraj' sometimes mentioned in the news is related to
• Meghraj is a Cloud Computing project of the government of India. The department of electronics and information technology (DeitY) has initiated the project 'Meghraj',. This project aims at creating the Government of India Cloud (GI-Cloud) computing environment at the national level.
• Cloud Computing Services provide the new model of offering services (Platform as a Service (PaaS), Infrastructure as a Service (IaaS), Software as a Services (SaaS) and Storage as a Service (STaaS)) to the users at fast pace which is also cost-effective.
